-Heated Pitot Tube: Screening Thermal Model

-Simplified lumped-differential formulation

-Adequate for screening and pre-qualification analysis

-Also relevant for thermal optimization analysis

-Aimed at future combination with ice accretion advanced modeling

19

- Proposed Screening Thermal Model

-One-dimensional transient formulation (thermally thin walls)

-Fin type equation with longitudinally variable area and perimeter

-Conjugated heat transfer with heat transfer coefficient correlations for incompressible & compressible flow

-Covalidation with wind tunnel and thermographic measurements

20

- Screening Thermal Model

-Solution Methodology: Generalized Integral Transform Technique (GITT)UNIT Code – v.1.5.2
