Abstract
Experimental heat transfer data for single-phase water flow in the annuli with corrugated inner tubes are presented. In the annuli with parallel flow, ten different annular arrangements are considered. For water flow rate in the range of 1,700 < Re< 13,000 , data for Nusselt numbers are presented. The results show significant effects of both the pitch to trough height ratio (P/e) and radius ratio (r*). As P/e becomes closer to 8 in the range below the radius ratio (r*) of 0.5, Nusselt numbers increase. However, Nusselt numbers decrease in the range above the radius ratio (r*) of 0.5 because flow reattachment position becomes farther in the narrower clearance.

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
