Conjugate Heat Transfer Simulations of a Nozzle Flow over a Film-Cooled Plate
Bibliographic record
Abstract
This paper presents Ansys Fluent results for a rectangular exhaust nozzle test case from the Fifth AIAA Propulsion Aerodynamics Workshop. The main objective of the workshop was to assess the aerothermal interaction of a heated air exhaust with a film-cooled plate downstream of a convergent nozzle exit, which is representative of engine exhaust flow applications with film cooling. Two sets of hierarchical computational meshes are employed. The first set of meshes consists of workshop-provided Pointwise® meshes. The second set of meshes is generated using Ansys Fluent meshing. Steady conjugate heat transfer simulations with radiation are performed to account for heat conduction through solid materials as well as the electromagnetic heat produced by the solid surfaces of the plate, plenum, and nozzle. Reynolds-averaged Navier–Stokes simulations using the shear-stress [Formula: see text] turbulence model are conducted for a workshop-defined nozzle condition, set point 42, using three blowing ratios. Computational fluid dynamics results are validated against experimental velocity and temperature measurements recorded above the film-cooled plate.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
