Effect of Gap Width of Rectangular Narrow Channel on Heat Transfer Enhancement
Bibliographic record
Abstract
Considering the structural characteristics of flow passage in the rectangular narrow channel and the annular flow predicted analytical model of Critical Heat Flux(CHF) in round tube, the annular flow CHF analytical model in rectangular narrow channel has been obtained. This model can be used to predict the CHF of boiling two-phase flow annular flow in rectangular narrow channel which gap width is not less than 0.5mm. The analysis and calculation indicate that when the inlet width-gap width ratio of rectangular narrow optical channel is 25～85, the enhancement of CHF in channel is obvious. At the same time, considering the characteristics of two-phase flow, the new determinant laws of CHF in boiling two-phase flow system has been derived. The analysis and calculation indicate that this determinant laws is appropriate. The best width-gap width ratio of heat transfer enhancement is 45～75. Based on the above results, the reference width-gap width ratio of heat transfer enhancement is 45～75 in rectangular narrow channel.

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.
