Heat and fluid flow downstream of a row of finite-height circular cylinders
Bibliographic record
Abstract
Induced turbulence created by a row of finite height cylinders is applicable in different engineering applications, e.g., for promoting convective cooling of solar panel. In this study, flow past a row of 13 side-by-side finite-height circular cylinders having a height-diameter (h/d) ratio of 2 (20mm/10mm) and center to center distance between adjacent cylinders (g) of 2d was scrutinized at a Reynolds number based on cylinder height of 4700 inside a wind tunnel over a flat plate. The flow at 5h and 10h downstream of the cylinder array was characterized using a 2-d hot wire anemometer. To understand the convective heat transfer from the hot plate, Nusselt number normalized by the reference no-cylinder case, Nu/Nu0, was deduced based on the temperature difference between the lower and upper surfaces of the hot plate. Significant heat transfer enhancement occurred which was explained in terms of flow properties. A regression analysis was performed, and it was revealed that the most influential parameters for enhancing heat transfer were the stream-wise turbulent intensity followed by the stream-wise velocity.

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.
