Report on ASME Journal ofFluids Engineering

By Malcolm Andrews, Technical Editor of the JFE

I am pleased to write this reportabout the progress with the ASMEJournal of Fluids Engineering (JFE).It has now been just over 16 monthssince I took over the Editorship ofthe Journal of Fluids Engineeringfrom Joe Katz, and it has been abusy time. In the paragraphs below I have taken the opportunity to

report the progress of the Journal, our current efforts toimprove responses to authors, and give some directions onhow best to submit articles. During 2010 the Journal had atotal of 426 submissions, of which to date 79 have beenaccepted and another 78 are in progress. These statisticscompare well with 2009, and indicate that we are on-track toaccept about 25% of papers submitted 2010. Moreover, dur-ing 2010 we had 5 Associate Editors finish their terms of service, and I send my sincere thanks for all the hard work toDrs. Ian Eames (2007–2010), Theodore Heindel (2005–2010),James Liburdy (200–2010), Chunill Hah (2006-2011), and

Ugo Piomelli (2004–2010). I am also pleased to announcethat 9 new Associate Editors have agreed to join the JFEnamely, Ye Zhou (2010–2013), Peter Vorobieff (2010–2013),Charlie Zheng (2010–2013), Ismail Celik (2010–2013), D. Keith Walters IV (2010–2013), Kendra Vail Sharp (2010–2013), Mark Tachie (2011–2014), Mark Duignan (2011–2014)and John Abraham (2011–2014). We also have recruited 2 guest editors: Ali Beskok (2011–2012) and Edward Son(2011–2012) to help with some special situation submissions.With our submission rate presently running at about 20%above 2010, all of the Associate Editors will be busy!

As with all fluid systems, the Journal is changing with the intent to increase submission, quality, and response to authors. To this end we have instituted a policy of Editor “pre-screen-ing” papers when they are first submitted to give quick feed-back about manuscripts that are obviously deficient. Suchdeficiencies typically include: poor English; formating asa con-ference publication rather than for the Journal {https://journal-tool.asme.org/Help/AuthorHelp/WebHelp/JournalsHelp.htm};“work-in-progress” rather than completed; “observational”conclusions rather than careful analysis and discussion; and,use of commercial softwareto create a “report” rather than anarchival set of results of value/use to the JFE readership. Tohelp authors with the criteria for use of commercial softwarethe JFE published an article {Andrews, M., “Guidelines for Useof Commercial Software and Diagnostics in Articles for theJournal of Fluids Engineering,” Journal of Fluids Engineering,vol. 133, iss. 1, pp 010201–010202.}, and I strongly encour-

(continued on page 3)

age authors to review that article forhelpful guidance and to pay attention tothe ASME requirement on reportingnumerical uncertainty {Celik, I.B., Ghia,U., Roache, P.J., Freitas, C.J., Coleman,H., et al, “Procedure for Estimation andReporting of Uncertainty Due to Dis-cretization in CFD Applications,” Jour-nal of Fluids Engineering, vol. 130, iss.7, pp 0780011–0780014.}. Further-more, Associate Editors have beenencouraged to do their own pre-screen,with more technical depth, prior to send-ing to reviewers, and to let authors (orthe editorial office) know of any defi-ciencies that might significantly impactthe likelihood of a successful review.The spirit of these pre-screenings is toprovide faster feedback to authors, andto provide better quality papers forreviewers to consider (our reviewers aresome of our future authors). Anotherinitiative is to encourage authors, whoseconference papers have been ranked“journal quality,” to consider extendingtheir paper and submitting to the Jour-nal (after formatting to the Journalrequirement). It is my experience thatmost conference papers report “work-in-progress” and typically need additionalresults before they become of archivalvalue. So the submission of a confer-ence paper straight to the Journal (afterthe conference) is likely to be unsuc-cessful under a pre-screen or review.However, I believe a closer coupling ofconferences to the Journal will prove beneficial to both. One last significantchange concerns excess page charges, these charges will no longer be assessed, but the (substantial) colorprint charges will remain. Thus, the previous limit of 9journal pages is no longer in effect, butauthors should be careful of excessivelylong papers where readers might loseinterest.

I close by thanking my editorial boardof Associate Editors and the editorial office for all their hard work. Please feel freeto contact the editorial office at JFE.EditorialOffice@gmail.com if you haveany questions. If you see me at a con-ference, please do not hesitate to visit. �

Fluid Mechanics Technical Committee (FMTC)

Javid Bayandor, Chair

Kamran Siddiqui, Vice-Chair

FMTC leads a broadspectrum of fluid

mechanics related activ-ities within the ASMEFluids Engineering Division (FED). TheCommittee oversees the organization of tensymposia during theFluids Engineering Division Summer Meet-ing (FEDSM) and foursymposia during theInternational MechanicalEngineering Congress &

Exposition (IMECE). In the past twoyears, the Committee has also workedwith the FED Executive Committee tohelp identify prominent plenary talks tocomplement its technical programs dur-ing the summer meetings in Vale, CO, in 2009 and Montreal, QC, Canada, in 2010.

The Franklin P. and Caroline M.Johnson Professor of Mechanical Engi-neering, Parviz Moin of Stanford Univer-sity was the FMTC’s invited plenaryspeaker for FEDSM2010. ProfessorMoin’s remarkable talk focused on “Highfidelity computation of complex turbu-lent flows,” which covered many aspectsof contemporary numerical issues aim-ing to predict the multi-physics of com-plicated turbulent phenomena. Duringhis talk, Professor Moin indicated theimportance of adherence to higher con-servation principles and grid quality thatcan help alleviate the adverse role thatnumerical errors can play when dealingwith turbulence-associated disturbances.Further to that, major examples in sup-port for the validations of the unstruc-tured mesh models developed by Profes-sor Moin’s team within the Center forTurbulence Research (CTR) were pre-sented.

The theme of the ASME, JSME,KSME Joint Fluids Engineering Confer-ence 2011, to be held between July 24to 29 in Hamamatsu, Japan, revolvesaround Industry-Academia-Governmentunder the banner of “Global Collabora-tion in Advanced Fluids Engineering:

Innovation for Sustainability, Environ-ment and Energy.” For this event,FMTC is proud to announce that Profes-sor James Riley, Professor of MechanicalEngineering and Adjunct Professor ofApplied Mathematics at the University ofWashington, will be the joint FMTC/ CFDTC invited plenary speaker. In histalk, Professor Riley will discuss “SomeFluid Dynamical Issues in the Siting ofTurbines for Tidal Energy.” Furtherdetails about the conference and itstechnical program can be found atwww.ajk2011-fed.org.

In the past year, the membership ofFMTC alongside the other FED technicalcommittees has had an opportunity torevisit its respective By-Laws approvedback in the year 2000. The new draftincorporating addendums to the terms ofoffice, new elections, and other commit-tee/sub-committee responsibilities andaffairs has been officially submitted tothe FED Executive Committee for con-sideration and approval. Additionally,an FMTC officer election, coinciding withthe summer meeting, was held in Mon-treal in July 2010. During this event,having completed her two year term inoffice, Professor Francine Battaglia fromVirginia Tech stepped down as the chairof FMTC. The FMTC members unani-mously thanked Professor Battaglia forher dedication and outstanding servicesto the committee. Under ProfessorBattaglia, FMTC became the first techni-cal committee to propose and adopt thesymposium-only format to unify theorganization of all its affiliated events.Professor Battaglia further made someimportant changes to streamline thetechnical activities of FMTC and facili-tate the promotion of the committee out-side FED and recruiting new members.She has since been appointed to theFED Executive Committee. Subsequentto Professor Battaglia’s departure, Pro-fessors Javid Bayandor from VirginiaTech and Kamran Siddiqui from the Uni-versity of Western Ontario were electedby the FMTC members as the chair andthe vice-chair of the committee, respec-tively. Javid Bayandor had served theprior two year term as the vice-chair ofFMTC and Kamran Siddiqui has been anactive member of the committee. Thenext election will be held duringFEDSM2012 in Puerto Rico.

Multiphase Flow Technical Committee (MFTC)

Mark R. Duignan, ChairTimothy J. O’Hern,Vice-Chair

To better understandcavitation, the ASME

Cavitation Committeewas formed in 1937,which has since evolvedto, and is currentlyknown as, the Multi-phase Flow TechnicalCommittee (MFTC).There is still a strongneed to understand theformation of pressure-created gas bubbles ona surface and thedestructive force caused

by cyclic stress due to bubble collapse,but in 2011 the field of multiphase, ormulticomponent, flow is much largerand more diverse.

The MFTC is made up of a group ofengineers, scientists, and especially

young professionals interested inadvancing knowledge in all aspects ofmultiphase flow. Because the area is sobroad it touches many other disciplines,to include Heat Transfer, Acoustics,Manufacturing, Combustion, Bioengi-neering, Micro/Nano-Electomechanicalsystems, to name a few. Our main vehi-cle to bring the multiphase communitytogether is to create, sponsor, andorganize symposia and fora at engineer-ing conferences: the InternationalMechanical Engineering Congress &Exposition (IMECE) and the Fluids Engi-neering Division (FED) Summer Meeting(FEDSM). The latter is the principalvenue for MFTC activities.

This year is shaping up to be veryexciting. The summer meeting,FEDSM2011, will be far reaching and for2011 is also known as AJK2011 [or theAmerican Society of Mechanical Engi-neers - The Japan Society of MechanicalEngineers - The Korean Society ofMechanical Engineers Joint Fluids Engi-neering Conference]. It will be in Hama-matsu, Japan, July 24–29 [see http://www.ajk2011-fed.org/]. Every fouryears the Fluids Engineering Divisions ofASME and JSME hold a joint conferenceand for 2011 this will be the 6th meet-ing. However, this year KSME will alsoparticipate, so that this will be the 1stjoint ASME-JSME-KSME FED meetingand the first time to be held in Japan.The MFTC will play an integral part ofAJK2011 with 5 symposia and 2 fora:

• 12th International Symposium ofGas-Liquid Two-Phase Flows

• 13th International Symposium onGas-Particle Flows

• 11th International Symposium onNumerical Methods for MultiphaseFlow

• 12th International Symposium onLiquid-Solid Flows

• Symposium on Non-Invasive Measurements in Single and Multiphase Flows (co-sponsoredwith FMITC)

• 46th Cavitation and MultiphaseFlow Forum

• Open Forum on Multiphase Flows:Work in Progress

MFTC will be also active at IMECE2011 in Denver, Colorado, Nov. 11–17 [see http://www.asmeconferences.org/Congress2011/] to include sponsoringtwo fora:

• 7th Forum on Recent Develop-ments in Multiphase Flow

• Noninvasive Measurements in Single and Multiphase Flows Flows(co-sponsored with FMITC)

Next year the MFTC will celebrate its75th year of existence and we hope to mark the occasion at FEDSM2012 to beheld in Puerto Rico. Come join us in 2011 and 2012 as we are always pleased to welcome new and active members.Please feel free to contact the chair,Mark Duignan at mark.duignan@srnl.doe.gov or the vice-chair, Tim O’Hern attjohern@sandia.gov. �

Micro- and Nano-Scale FluidDynamics Technical Committee(MNFDTC)

Prashanta Dutta, ChairDavid Sinton, Co-chair

It was another greatyear for micro- and

nano-scale fluid dynam-ics at the IMECE. Thisyear the micro/nanofluid dynamics sessionshad a total of 59 talks

with 27 papers presented in Track 10-11and 32 papers presented in Track 13-9.The sessions were well attended andthere was excellent discussion followingthe talks. Canadian members of thetechnical committee advertised theForum extensively to increase involve-ment of Canadian researchers in theconference, and the contributions fromCanada were up significantly as a result.The 2010 Microfluidics forum wasorganized by Peter Huang of Bingham-ton University with help from Chang-Hwan Choi of Stevens Institute of Tech-nology, and David Sinton of University of

Victoria. Chang-Hwan is taking the leadfor 2011, with help from Jiang Zhe.

Invited talks are an important part ofthe IMECE meeting, and this past year the Forum attracted outstandingresearchers Dr. Paul Yager and Dr. CarlHansen to the event. Dr. Paul Yager is a world-leading researcher in microfluidics, and microfluidics for public health, andhe gave a talk on “Point-of-Care Diag-nostics for Global Health”. Dr. CarlHansen is an established expert inmicrofluidic systems for applied and fun-damental research in genomics and cellbiology. Carl gave a talk on “Microflu-idic Tools for Studying Single CellResponses”. Both researchers gave aninteresting and engaging talk and partic-ipated in discussions and networking.These speakers were brought in by thekeynote committee of David Sinton,Prashanta Dutta and David Erickson.This coming years’ invited talks will beorganized by Kendra Sharp, PrashantaDutta and David Sinton.

For the first time this year, the Forumfeatured a Microfluidics Social. Thesocial event was scheduled immediatelyfollowing the technical committee meet-ing, and was held in the lounge of theFairmont Waterfront Hotel. The socialwas well attended by students, faculty,and invited speakers and was a great chance for attendees to meet and network in a relaxed setting. As the responsewas very positive, the committee isadding this function to future events.

The Forum also has two awards: aBest Paper Award and a Best StudentPresentation Award. Prof. Steven Were-ley’s group was awarded the Best PaperAward for their work on the “Applicationof an Optically Induced Electrokinetic Manipulation Technique on Live Bacteria.” Carlos Escobedo was awarded the BestStudent Presentation Award. To selectthe best presentations and papers, feed-back from session chairs is collectedand compiled by the awards committeeincluding David Sinton, Prashanta Duttaand Kendra Sharp.

The Micro/Nano Society-wide PosterForum was also a success this year andattended by many Microfluidics Forumparticipants. This forum, organized byTony Huang, has become an importantpart of the conference experience for theMicro/Nano community.

This year the Fluids EngineeringSummer Meeting is being jointly spon-sored with the Japanese Society ofMechanical Engineers and the Korean

Society of Mechanical Engineers inHamamatsu, Japan. Prof. Steve Wereleyis coordinating the Microfluidics Forumon behalf of the ASME Micro/nano FluidDynamics Technical Committee. A num-ber of the MNFDTC committee membersare participating either by presenting keynotes or presenting oral or poster sub-missions. Prof. Min Jun Kim, Drexel University, will run the Micro/nano FluidDynamics Technical Committee meetingin the Fluids Engineering Summer Meet-ing.

In 2011, the IMECE will be held inDenver, Colorado, and the organizers arecurrently processing the papers and ses-sions for this event. The Micro and Nano Fluid Dynamics Technical Committee islooking forward to the meeting andbroadening the impact of the division. �

Computational Fluid DynamicsTechnical Committee (CFDTC)

Z. Charlie Zheng, ChairRaymond Gordnier,Vice Chair

While the CFDTCwas revising the

Bylaws, it was interest-ing to find out some history of the TC. Thecommittee originated as

the Coordinating Group on Computa-tional Fluid Dynamics (CGCFD) in 1988within the FED. In July 2002, theCGCFD was renamed the CFDTC by theFED. The focus of the CFDTC is thefield of computational fluid dynamicsand related areas. The overall objectiveof the CFDTC is to develop, promote,coordinate and disseminate informationrelating to the successful and accurateapplication of CFD to problems of inter-est and importance to the research com-munity as well as to industrial users andother practitioners. Membership is opento anyone who is interested in participat-ing in the activities of the CFDTC.

The CFDTC usually meets two timesa year: one at the summer FED meeting and the other at the IMECE meeting. This last year these two meetings happened to be both in Canada. We met in Montrealin August and Vancouver in November.

At the Montreal meeting, the CFDTCsponsored 6 symposiums: 10th Sympo-sium on Applications in CFD, Sympo-

Fluid Measurements and Instrumentation Technical Committee (FMITC)

Pavlos Vlachos,ChairHui Hu, Vice Chair

The mission ofthe Fluid Mea-

surement andInstrumentation Techni-cal Committee (FMITC)is to provide a venue forthe Fluids EngineeringDivision (FED) to focuson measurement andinstrumentation issuesrelevant to fluid flows.Modern fluids engineer-ing embraces a com-

plex spectrum of problems from the rel-atively simple case of isothermal,incompressible, single phase flow ofNewtonian fluids to non-Newtonian mul-tiphase flows with heat and mass trans-fer from the nanoscale to themacroscale. Experimental measure-ments and instrumentation are required

in all cases to verify new theories, tocertify the performance of fluid machin-ery, or to obtain fundamental informa-tion on processes to guide and validatethe development of analytical andnumerical models.

The FMITC was originally organizedunder the Coordinating Group for FluidMeasurements (CGFM) for the purposeto foster technical and professionaldevelopment activities in the area offluid measurements in both laboratoryand field measurements. FMITC isresponsible to organize, promote, andpresent symposia, forums, and paneldiscussions on fluid measurements. Thecommittee meetings of FMITC are heldtwice a year at the IMECE and the FEDSummer Meeting. The time and date ofthese meetings are announced in theconference program.

In the summer of 2010, FMITC hasrevisited its By-Laws approved back inthe year 2000. The revisions includeaddendums to the terms of FMITC offi-cers, new elections, and other commit-tee/sub-committee responsibilities andaffairs, which has been officially submit-ted to the FED Executive Committee forapproval. FMITC officer election, coin-ciding with the FED summer meeting,was held in Montreal, Canada in July2010. After having chaired the FMITCfor the past 4 years, Professor Ted Hein-del from Iowa State University steppeddown as the chair of FMITC. The FMITCmembers unanimously thanked Profes-sor Ted Heindel for his exceptional serv-ice to the FMITC committee. ProfessorPavlos Vlachos from Virginia Tech andProfessor Hui Hu from Iowa State Uni-versity were elected by the FMITC mem-bers as the chair and the vice-chair ofthe committee, respectively.

FED Summer meeting in 2011 is co-organized by ASME, JSME and KSMEand is referred to as AJK 2011, whichwill be held on July 24-29, 2011 at Hamamatsu, Japan. FMITC will organize following symposium and forum as an integral part of the AJK2011 conference:

• Symposium on Non-Invasive Measurements in Single and Multi-phase Flow

• Forum on Fluid Measurements andInstrumentation

Further information about the sympo-sium and forum is available at http://www.ajk2011-fed.org/

FMITC will also be active atIMECE2011 to be held on Nov. 11–17,2001 at Denver, Colorado to organize or

co-sponsor following forums and sym-posiums:

• Fluid Measurements and Instru-mentation

Currently, theSenior Member and Secretary of theExecutive Committee are the designatedrepresentatives, and we serve for oneyear. The MAL representatives eachserve for a three-year term. Additionaldetails of BETG may be found on theASME web page at http://divisions.asme.org/BETG/. The BETGOB conducts itsroutine business by email and monthlytelephone conference calls.

The BETGOB meets in person threetimes a year, once at IMECE and twice atthe Congress of Divisions (COD), whichis a meeting of all divisions within ASME.Our first meeting of COD was in Newark,New Jersey, on September 24 and 25,2010, and the second in Dallas, Texas,on March 3, 2011, in conjunction withthe 2011 Leadership Training Conference(LTC). On the morning of March 4, wehad an informal breakfast meeting withother members of the FED ExecutiveCommittee that were in attendance at theLTC. The attendees included AwatefHamed, Dave Halt, Jinkook Lee, GeorgePapadopoulos, and myself. One of thetopics of discussion was the location ofFEDSM2013. Awatef will the conferencechair. George (FED Chair 2007–08) iscurrently the Vice-Chair of the BETGOBand will become Technical Group Leaderin the near future. Incidentally, KumarRohatgi(FED Chair 2002–03) is the MAL

for Division Operations.One of the principal objectives of the

BETGOB is to influence ASME policiesfavorable to the divisions. Prior to mytenure on the BETGOB was the imple-mentation of the on-line copyright formfor our conferences. Over the past year,ASME has implemented a new confer-ence policy, ASME Policy 12.1, whichimpacts our conferences. For additionalinformation on conference planning, seethe ASME Conference Planning Commit-tee (CPC) web page: http://committees.asme.org/K&C/CPC/home.cfm. OurMAL representative is Vikas Prakash ofCase Western. The CPC is in theprocess of developing a web tool for theconference planning process. The datefor the implementation of the new webtool has not yet been established.

The BETGOB has been approvingbylaws for the divisions including its

own. The bylaws of the Materials Divi-sion were the most recent to beapproved. The FED bylaws will be thelast to be approved of the six divisionswithin BETG. The last FED bylaws wererevised in April 1994. Jim Liburdy overthe past year has been working onupdating the bylaws of the FED Techni-cal Committees. Jim’s effort and thesupport of the Technical Committees aremuch appreciated. I am currently re-writing the bylaws of the ExecutiveCommittee. The bylaws are beingupdated to incorporate our current oper-ations and to conform to Robert’s Rulesof Order. The Technical Committeebylaws and Division operating proce-dures will be added as appendices. Ifyou have any questions or commentsabout BETG, please contact myself orJinkook Lee. �

2011 ASME-JSME-KSME Joint Fluids Engineering ConferenceACT Congress Center

Hamamatsu, Japan July 24–29, 2011

The ASME-JSME-KSME Joint Fluids Engineering Conference 2011 (AJK2011-FED) has grown out of the ASME-JSME Joint Fluids Engineering Conference that was first held in Portland, Oregon in 1991. From a global per-

spective, the world faces a number of daunting challenges including global climate change, finite energy resources,and economic crises. These problems are wide-ranging and extremely complex. Mechanical engineering andmechanical engineers have the potential to overcome these problems. Three mechanical engineering societies,JSME, ASME and KSME, have been addressing these problems both individually and collaboratively. The ASME-JSME Joint Conference on Fluids Engineering has played a major role in addressing these challenges, but the prob-lems are too complex to solve only through bilateral collaboration. We need global and industry-government-acade-mia collaboration to find the answers. On this basis, the three societies have decided to hold the ASME-JSME-KSMEJoint Conference on Fluids Engineering 2011 (AJK2011-FED) in Hamamatsu, Japan. The organizing committee ofAJK2011-FED looks forward to the active participation of mechanical engineers and researchers from around theworld. There are currently over 800 technical papers in process for this conference.

The AJK conference will be held as scheduled. Please be assured that the conference venue, Hamamatsu, is verysafe as it is far away, or 530 kilometers from Fukushima. For access, Central Japan International Airport is the near-est airport to the venue.

Introduction

According to Lefebvre1 and Liene-mann, Shrimpton, and Fernandes2,

the earliest quantification of jet disinte-gration was carried out by Felix Savartin 1833. Since that time, the breakupand atomization of jets has been ofdirect importance to, and the subject ofgreat experimental and computationalfocus within, the agricultural, chemical,food, fire protection, and energy-produc-tion industries. In the present work, anairblast nozzle (injector) is used to gen-erate an atomized fuel stream for alarge-scale reactor. Three streams areused: inner jet gas, outer annular gas,and an intermediate annular liquidstream. An extremely rich body of pre-vious experimental and computationalwork on thinning sheets and coaxial jetsexists in the open literature. More can be found in Strasser et al.3 and Strasser4. In short, a study directly related to thepresent work has not been found in theopen literature. The objective is to carryout an air-water test stand (AWTS) anda compressible (Mach number >1) VOF-based (geometric reconstruction) CFDstudy of an airblast atomizer. The pres-ence of three streams in certain combi-nations produces an inherently unsteady,bursting flow field that requires carefulstatistical consideration. The effects ofvarious stream flow combinations on thepressure response, flow field, and spraydistribution are considered. More than40 geometric and stream combinationpermutations have been tested over thepast year as part of the overall experi-mental program, but only 7 will be dis-cussed here. The 7 flow combinations(FC) involve changes in overall rate(involves all flows) and progressivelyincreasing inner air (IA) flow rates (withthe other two held constant). In generalhigher FC designations imply a relatively larger amount of IA. Details on the AWTS and the computational method, including numerics, meshing, convergence, axi-symmetric versus 3-D models, and time-averaging issues, can be found in Strasser4.

Pulsatile Annular Liquid SheetThe annular liquid film is excited by

perturbations from both the inner andouter gas streams. Liquid can be seen

peeling off outer and inner edges as wellas bulk film fragmentation into liga-ments (Dumouchel5). There are at least3 annular film driving frequencies in playhere: i) shedding on the outside of thefilm layer from the OA (very fast), ii)shedding on the inside of the film layerfrom the IA (relatively slow), and iii)bulk flapping of the film layer (some-where between the other two). Periodi-cally, but not necessarily at regular inter-vals, the three frequencies tune togetherto produce five different types of pulsa-tion events:

1. “Normal” bursts – The spray comesaxially down away from the feedinjector and then spreads normal tothe feed injector face. The burstthrows droplets radially outward. Itcan be seen in CFD and the AWTSvideo that this occurs at a frequencyof about 200 Hz. A series of thesecan be observed occurring in the“Christmas tree” pattern in Figure 8.

2. “Half” bursts – For this event, thespray is only slung radially outwardabout half the radial distance of thatof the normal burst. There aremaybe three of these events occur-ring for every normal burst.

3. “Necking only” – Here, the streamradially narrows, but no outwardbursting event occurs. There areapproximately nine of these eventsfor every normalburst.

4. “Blowback” –Approximatelyevery 50 or sonormal bursts is ablowback event,when the spray isthrown so violent-ly outward thatsome of it actual-ly moves axiallyin reverse andsplashes back onthe injector face.The strength and frequency of these events dependsstrongly on FCand feed injectorgeometry.

5. Inner gulps –This can only be

observed in the CFD videos since theAWTS videos only allow the visuali-zation from the outside of the spray.In this event, liquid bridges over theIA stream and is splashed back upinto the IA inlet. The gulps occur ataround 80 Hz.

Spray Pattern MetricsThe three spray pattern metrics for

bursts are shown in Fig. 1. AWTS videosnap shots are shown on top of CFDvideo snapshots. The only differencebetween the left and right is just that dif-ferent dimensions are being highlighted.A" is the “neck width”, B" is the “neckdistance”, and C" is the “shoulder dis-tance.” The neck width is measured atthe thinnest neck of an event, at whichpoint the neck distance off the injectorface is also measured. The shoulderdistance is measured from the injectorface to the outer edge of the spray at theonset of another burst event. Of course,the AWTS videos show more dropletswhile CFD videos show more ligaments, so any metrics need to be comparable to one another from both video methods.It was for this purpose that these partic-ular metrics focus on the continuouspart of the annular liquid sheet. Manualframe-by-frame analysis is required tofirst find the event, and then to take saidmeasurements. A series of multivariate

analyses of variance (MANOVA) werecarried out.

• For measures A" and C", the valuetends to be reduced by an increase inIA. This is counter-intuitive and saysthat the opening of the spray byincreasing inner air tends to makenarrower bursts closer to the feedinjector face.

• For measure B", the value tends toincrease with increasing IA. This ismore intuitive and says that the open-ing of the spray by increasing innerair tends to make bursts occur fartheraway from the feed injector face.

Water Collection Profiles (Spray Angle)

Water collection in the AWTS andCFD took place in an attempt to makedirectional comparisons in the effect ofFC on spray angle. The project involvedmany more permutations than thoseshown here, and project duration was ofimmense importance. Figure 2 showsthe resulting AWTS water collection pro-files for FC3, FC5, FC6, and FC7. Theonly difference between an “A” and “B”curve, where applicable, is that the datawere taken at different times. Environ-mental conditions played a role in theresults, although each “A” profile wasreasonably close to its “B” counterpart.FC3 clearly has a unimodal distribution,FC5 has a trimodal distribution, and FC6(high IA, low rate) has somethingbetween a bimodal and trimodal distri-bution; it is either a weak trimodal or anoff-center bimodal. In any event, FC5 isalmost indistinguishable from FC6. FC7(high IA, high rate) seems to be leaning

back towards unimodal, but remains tri-modal with an extremely strong centerpeak. This is especially interesting,because it implies there is a strong inter-action between overall rate and IA. Ifthe profile is not shown here, it can beassumed that it was unimodal. Overall,this says that the IA has to be above thecritical regime in order to produce amultimodal profile. The CFD profilescan be found in Strasser4.

Conclusions

An experimental and computationalprogram has been executed to charac-terize the flow field produced by a three-stream airblast reactor injector at vari-ous stream flow combinations. In short,our CFD method (at this stage of devel-opment) cannot be used as a replace-ment for AWTS work, but it can be usedto "screen" designs before spending thetime and money to test them in theAWTS. Much more frequency spectraanalysis can be found in Strasser.4

• Three distinct frequencies are at playto produce a liquid spray: sheddingat the outer air/film interface, shed-ding at the inner air/film interface,and the bulk flapping of the annularliquid film. The tuning of these three driving frequencies produces five types of pulsation events: normal bursts,half bursts, necking only, blowback,and inner gulps. The existence andfrequency of these events depend onthe stream flow combinations.

• Depending on the relative amount ofinner air flow, there seem to be threeoverall flow regimes. Low IA flows

produce regular normalbursts. Moderate IAflows produce all fiveburst events along withviolent AWTS feed pip-ing network pulsations.Higher IA flows produceall five events, but donot exhibit violent feednetwork pulsations.Somewhere near 0.71IA flow appears to bethe transition point, andit shows the largestfluctuations in IA feedpressures. Removingthe IA completely caus-es bursts to stop alltogether. These areconsistent between theAWTS and CFD.

• Water spray collection profiles fromAWTS reveal that at low IA flows, thespray pattern is unimodal. At higher flows it becomes bi- or trimodal. There might be an interaction between IAflow and overall air delivery. TheCFD spray pattern results track someof the AWTS flows directionally, whilenot others. Both sets of results showmultimodal results above 0.71 IAflow.

• Three different video analysis “met-rics” of the spray shape and burstquality were determined useful forquantifying the effect of inner air.They echo the fact that burstingbecomes more dramatic with increas-ing inner air. CFD results correlatewith one of the AWTS metrics.
