Flow Relaxation Past a Transverse Square Rib in Pressure Gradients
Bibliographic record
Abstract
An experimental investigation is undertaken to study the salient features of separated and reattached flows over a transverse square rib in an asymmetric diverging and converging channel. To facilitate comparison, experiments were also performed in a parallel-walled channel for which the pressure gradient is nearly zero. The transverse square rib was located 1000 mm from the inlet of a given channel (at the inlet to the convergence/divergence section). A high-resolution particle image velocimetry was used to conduct the velocity measurements. From these measurements, isocontour plots of mean velocity, Reynolds shear stress, and spanwise vorticity in the vicinity of the rib were reported. The profiles of mean velocities, Reynolds stresses, triple products, and some of the terms in the transport equations for turbulent kinetic energy and Reynolds shear stress are reported in the separated and redevelopment regions as far downstream as 200 step heights.

How this classification was reachedexpand
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.
