Experimental investigation of heat transfer effects in impinging circular jets confined by inclined plates
Bibliographic record
Abstract
In this study, the effects of heat transfer in turbulent flow fields of impinging circular jet confined by inclined plates were investigated experimentally. Temperature distributions on the impingement plates were acquired with thermal camera. Temperature measurements were carried out on the impingement plate in four different impinging circular jet flow setups confined by plates with inclination angles of θ = 0°, 15°, 30° and 45°, with an inter-plate spacing of 0.5 ≤ H/D ≤ 10 and a Reynolds number range of 20,000 ≤ Re ≤ 30,000. The effects of confinement plate inclination angle, intervals among plates and Reynolds number on the Nusselt distributions of the impingement plates were examined. It was found that Nusselt values on the impingement plate increase with increasing Reynolds number and decrease with increasing intervals among plates. Secondary top points become visible in the Nusselt distributions on the impingement plate at H/D ≤ 3 values of the inter-plate spacing. The position of the secondary top points on the impingement plate move towards the ends of the impingement plate with increasing inclination angle of confinement plate.

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.
