As I prepare this season’s greetings toall our alumni and special friends,there are about 40 days left in the1900’s. Many are franticallypreparing for the expected Y2Kglitches. The Department has donedue diligence in preparing for Y2Kand I do not expect our alumnidatabase to “disappear” on January 1.In fact, I do not foresee anyproblems with our departmentcomputer, instrumentation, andelectronic systems.

Personnel changes are occurringrapidly. Prasanta Kalita joined theSoil & Water faculty this fall. MarkMohr is now handling the PesticideApplicator Training (PAT) program.Al Hansen will be moving his familyfrom South Africa to join the OREESection by January 1. We are near theinterview stage in identifying areplacement for Bruce Litchfield’smove to the College of EngineeringDean’s office. Applications arecoming in for the Extension positionin Precision Agriculture and withKent Mitchell’s pending retirement,we must begin a search to fill his“very large” shoes.

As you can surmise, our Departmentis quickly taking on a new “youthful”look. With Kent Mitchell’s announce-ment of retirement on March 1, 2000the Department closes out a majorchapter of history and tradition. Withme as the only possible exception, ourfaculty are relatively young and areestablishing a new culture and legacyfor the 21st century. We will build onthe strength and reputation of ourformer faculty to maintain aDepartment that is relevant to thetimes but maintains the standard ofquality that have been established byour previous faculty, staff andstudents.

Students remain our primary focusand we continue to attract qualitystudents at both the undergraduateand graduate level. Our two studentclubs remain very active and againplaced very high in the ASAE EMIcompetition. This year we are alsoserving as the official departmenthome for the SAE Mini Baja designcompetition. The students areprovided an 8 Hp engine and build avehicle around the engine. Last year’steam placed sixth out of about 90entries in the midwest competition.

Happy Holidays!

2 December 1999

The evening of October 12 was a good night for the AgriculturalEngineering Department! At the 1999 Annual Extension AwardsBanquet held in Urbana, Illinois, two of our faculty received well-deserved awards.

Dealing with a major challenge is often eased by having the rightperson in the right place at the right time. Such was the case witha new state law mandating producer education on livestock wastemanagement and the response led by Ted L. Funk, ExtensionSpecialist in Agricultural Engineering. Ted’s response and hisleadership role in developing the Certified Livestock ManagerTraining Program, along with other achievements during his19-year career, earned him the Sustained Excellence inExtension Programming Award.

The Certified Livestock Manager Training Program is one in aseries of successful efforts by Ted over his Extension career toserve agriculture. Each year he responds to about 150 telephonecalls and letters from producers on topics related to animal waste.He has accumulated data that helps producers better managewaste lagoons, and he obtained funding for a research projectthat seeks to develop a new type of variable-rate slurry spreaderthat will enable farmers to ensure the environmentally correctrate of manure application on land.

Ted’s enthusiasm, creativity and dedication make him the rightman at the right place at the right time for the Illinois livestockindustry.

We are spending a significant amountof time thinking about how to betterprepare our students to handle issuesof the next century. The technology,skills and competencies required ofgraduates is a lot different than it wasfor most of us that graduated morethan 10 years ago. We are challengedto stay ahead of these rapidlychanging times. Informationtechnology is now dominatingeverything we deal with. FormerHeads indicate that mail and phonecalls controlled their lives. Nowemail is the preferred mode ofcommunication and dominates myoffice time.

We are planning to host an alumnireception during the ASAE Interna-tional meeting next summer atMilwaukee (July 9-12). Plan to attendand meet our new faculty as well asvisit with “old” friends and acquain-tances. Details will be in the summernewsletter.

We really enjoy hearing from alums.Please send us information aboutnew happenings (marriages, babies,job changes, etc.) E-mail makescommunication very easy. Also stopby for coffee when you are comingthrough this area. Have a blessedholiday season!

A Nationally Recognized Program …

In the mid-1990s, the rapid expansion in the size of livestock operationsand vertical integration collided with environmental concerns. Accountsof manure spills in North Carolina, Iowa and Missouri raised publicawareness of potential problems and created a need for new programs.The new Illinois Livestock Management Facilities Act put in place a newstructure of requirements and accountability, but no programs to meet itsprovisions.

Extension’s Manure Management Team stepped forward with a series ofprograms that explained new regulations to producers and prepared themto meet the new standards. The approach was multidisciplinary withrepresentatives from the Departments of Agricultural Engineering, AnimalSciences, Crop Sciences and Agricultural and Consumer Economics.

The representatives from Agricultural Engineering – Ted L. Funk andRandy Fonner, Extension Specialist, CLMP Facilitator, received theOutstanding or Innovative Program – Group for the “ManureManagement Team.”

Philip Buriak, ProfessorAgricultural Engineering andCoordinator of Technical SystemsManagement is a 1999 recipient ofthe National Excellence in Col-lege and University Teaching inthe Food and AgriculturalSciences Award. This prestigiousaward is sponsored by the UnitedStates Department of Agriculture(USDA) and the National Associa-tion of State Universities and Land-Grant Colleges. The national award,one of two given each year, includesa stipend to be used by the recipientfor the improvement of teaching athis college or university.

The GraduateFellowshipRecognitionProgram was heldon November 4,1999 and five ofour graduatefellows wererecognized.Pictured left to right Dr. Loren Bode, Head of Department,Eric Benson, Ana Maria Garcia, (seated) Jason Kwiatkowskiand Keli Christopher (not pictured, Mark Wilkins.)

The American Association ofCereal Chemistry (AACC)held its annual meeting inSeattle, WashingtonOctober 31-November 4.

Steve Eckhoff, Professor inthe Food and BioProcessEngineering Division, re-

ceived the AACC Excellence in TeachingAward. The award is presented to anAACC member and current teacher whohas made significant contributions throughteaching in the broad field of cereal scienceand technology. Christy Thompson,graduate student in the Food andBioProcess Engineering Division, won theCorn Refiners Association poster competi-tion. Her poster is based on her currentmasters work and was entitled, “Recovery ofSolids and Nutrients Contained in Corn WetMilling Coproduct Streams.” Posters werejudged by a panel for content, appearanceand also for the verbal presentation by thepresenter.

High Efficiency Aerodynamic Dedusterfor Air Cleaning

Yuanhui Zhang, Associate Professor, Bioenvironmental Engineering

The Issue: Primary health problemsassociated with indoor environment,especially confinement animalbuildings stem from a complexmixture of hazardous airborne dustparticles carrying ammonia, bacteriaand odors. Dust in animal buildingshas three unique characteristicscompared with other types of dusts:biologically active, high concentra-tion and odor carrier. Particlessmaller than 10 microns, so calledrespiratory particles, are responsiblefor the chronic respiratory diseasesin farmers and Sick Building Syn-drome (SBS) in residence buildings.These respirable particles are verydifficult to remove from air streams.The dust concentration in a pigbuilding is typically tens to hundredstimes higher than a residentialbuilding, thus making the conven-tional air cleaning technologies, suchas filtration and electrostatic precipi-tation, not practical. Existing cyclonedust separators require at least 500Pascal (2-inch water) pressure tooperate. These high pressuresprevent the cyclone from applicationin indoor environments, as most fansin animal buildings have a cut-offpressure of less than 250 Pascal (1-inch water). Even more impractical,particles smaller than 10 microns cannot be separated at that high pres-sure because of the strong turbu-lence associated with the highpressure.

The Research: We have developed aunique aerodynamic uniflowdeduster to separate particles in airstreams. The device, unlike theconventional cyclones, can remove

respirable particles at pressures aslow as 50 Pascal. With a betterunderstanding of fluid dynamics andparticle physics, the deduster em-ploys a set of turbine-type vaneguides, an involute separationchamber and a flow convergingsection to minimize turbulence andreduce the pressure loss. Figure 1shows the particle separation effi-ciency of a 288-cfm prototype in aswine building. The cut-size, whichis defined as the smallest particlediameter at which the separationefficiency is 50 percent, is about 4microns. In terms of particle countconcentration measured usingparticle counters, the particle separa-tion efficiency of the deduster was90 percent for particles larger than10 µm and 77 percent for particleslarger than 7 µm. In terms of massconcentration measured using masssamplers, the particle separationefficiency was 85 percent. Becausemost of the dust mass is attributedto the larger particles, the numberseparation and mass separationefficiency agreed very well. Re-search in progress includes applyingprinciples of molecular diffusion andparticle coagulation to remove

undesirable gaseous molecules suchas ammonia and odor in the airstream. Preliminary results showsthat it can remove 60 percent ofgaseous ammonia (in addition to theammonia attached to particles) in theair stream.

The Application: The dedustercould be an effective technology toreduce the dust and odor emissionfrom animal facilities. A widerapplication of the deduster may befound as an indoor air cleaner forresidential and office buildings.Americans spend 97 percent of theirlifetime indoors (including fourpercent in vehicles), and there is anincreasing awareness and concern ofindoor air quality and Sick BuildingSyndrome. There are estimated onemillion “sick buildings” (buildingswith poor air quality) housing 70million people in the U.S. With anautomatic flushing (timer-controlled)system, the deduster requires mini-mum maintenance and can be easilyincorporated into the existing airsupply systems in residential andoffice buildings. You may not needto change furnace filters at homeanymore.

Dedication and determination. Thatis what can be said about the 1999UIUC SAE Mini Baja team. Learn-ing from their mistakes in the 1998Mini Baja season, the 1999 UIUCSAE Mini Baja team set out with theintention of designing, building, andcompeting an award winning minibaja car. In the competitions theywould enter, the team would settlefor no less than top ten in theendurance race and top ten overall.

The 1999 season startedwith some key organizationand planning. It took somedetermined work from thebusiness team to findsponsors that would helpfinance the new car. Noth-ing but dedication and hardwork came from the designteams in designing this newcar. It was chosen to iterateoff the 1998 car due to itssuperior handling character-istics, but fix and fine-tunethe flaws. The 1999 car, named“Digger” would incorporate anindependent, front dual a-armsuspension with a solid swing-armsuspension in the rear. The V-BeltCVT was used again for its reliabilityand performance advantage and1999 would be the last year that SAEMini Baja would be using the 8horsepower engine. Since the powerwas fixed, weight conservation wasof utmost concern. The initial goalwas to keep the weight under 300pounds, something unheard of inMini Baja competitions. The designconcluded in November 1998, andthe construction began in December.By bending and TIG welding the

chomoly tubing and reducing weightwherever possible, Digger’s race trimweight was 310 pounds.

In addition to building a Mini Bajacar, the UIUC SAE Mini Baja teamwon first place awards for theirdisplay in the University of IllinoisEngineering Open House. They alsotook some time to travel to highschools and talk to students aboutuniversities and getting involved inSAE activities.

In April, the team traveled to KansasState University, in Manhattan,Kansas, site of the 1999 SAE MiniBaja West Competition. The teamhad been to the 1997 West competi-tion, but we were determined tobring some hardware back to theUniversity of Illinois. In the firstday, the team displayed Digger instatic judging and presentations,where they were awarded a 5th placein design. With some quick thinkingand acting, the team passed techjudging and was ready for thedynamic events. The second dayconsisted of the initial dynamic

runs, and the maneuverability course.After it was all said and done, theUniversity of Illinois ended the dayon top of the world with a first placein maneuverability, first place in hillclimb, third place in acceleration, andfirst place overall! The final day ofcompetition was the dreaded endur-ance event. UIUC started on theoutside pole position, and made afew laps before a brake line broke.After a quick fix and change ofdrivers, Digger made a few moreflawless laps before being refueled.About 2/3 through the race, aserious design flaw was found when

Digger destroyed thedriveline and ended the day.That driveline failuredropped the team to 21stin the overall rankings (outof 70 teams), but the teamwas taking home all theirfirst place dynamic awards,something that the UIUCSAE Mini Baja team hasnever done before.

After a thorough preppingof the car and some testing

time, the team headed to Dayton,Ohio, home of the 1999 SAEMidwest Competition. The first dayconsisted of the static judging, wherethe UIUC garnished a 3rd place inServiceability. The second day ofdynamic events concluded withmediocre performance in the hillclimb and acceleration, and also theproblem with the driveline aroseagain, but in a different place. Withsome hard work, Digger was fixed,and this time for good. The endur-ance race started with UIUC abouthalf way back in the field. Withsome persistent but conservativedriving and pit time, the teamfinished the day in the top tenevents – the hill climb, acceleration
