Abstract
The combined effect of waviness and porous media on the convection heat transfer and fluid flow characteristics is numerically investigated. Two models of wavy walled channel fully filled with homogenous porous material are assumed. The first was the symmetric converging-diverging channel (case A), and the second was the channel with concave-convex walls (case B). The governing equations have been solved on non-orthogonal grid, which is generated by Poisson elliptic equations, based on ADI method. Nusselt number values are used to indicate whether any cases of corrugation studied may have led to an increase in the rate of heat transferred compared with the planar surface channel which is the purpose of the study. The results show that case A gives more enhancement in heat transfer than case B. However, the thermal performance of the wavy channels (cases A & B) is better than the straight channel (simple duct).

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 it
