Abstract
This paper presents a study of turbulent mixing in two-dimensional confined impinging streams. A new composite turbulence model is proposed and verified by comparing its predictions with available experimental impingement heat-transfer data as well as the experimental temperature distributions in impinging streams obtained in this work. Better agreement between experimental and numerical impingement heat-transfer results predicted by this new model is noted compared to those predicted by two other low-Reynolds number k − ε turbulence models. The model was then used to perform a parametric study of the thermal mixing characteristics of two-dimensional turbulent confined impinging streams. It is found that both the operating and geometric parameters of the system have strong effects on mixing in impinging streams.

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
