Numerical Analysis of Temperature-Dependent Thermal Boundary Layers in Falkner-Skan Flow of Viscoelastic Fluids
Bibliographic record
Abstract
This study numerically investigates the Falkner-Skan thermal boundary layer for viscoelastic fluids, focusing on the influence of temperature-dependent material properties on flow and heat transfer dynamics. Using a second-order viscoelastic constitutive model, coupled heat transfer and boundary layer equations were solved to account for variations in viscosity, thermal conductivity, and specific heat with temperature. Realistic boundary conditions, including constant temperature and constant heat flux, were implemented. Results indicate that increasing the first normal stress coefficient from 0.5 to 1.5 expands the thermal boundary layer thickness by 25%, while Prandtl numbers ranging from 1 to 50 reduce boundary layer thickness by up to 40%. Favorable pressure gradients enhance heat transfer, leading to a 30% increase in the local Nusselt number along the wedge. These findings provide critical insights into the thermal behavior of viscoelastic fluids, with applications in optimizing heat transfer processes in polymer extrusion, chemical reactors, and industrial coating systems.

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.
