Abstract
4A particle image velocimetry system was employed to study the characteristics of turbulent wake generated by a single and a pair of identical rectangular cylinders at incidence in an open channel. Each cylinder has a nominal thickness, d = 9 mm, length, L = 36 mm and height, H = 190 mm. The experiments were performed for the following angles of incidence: α = 0°, 10°, and 20°, and at a centre-to-centre spacing of b = 50 mm for the cylinder pairs. The flow depth was 125 mm, and the Reynolds number based on the freestream velocity and cylinder thickness was 2925. The results reveal that the mean velocities, turbulence quantities, and wake half-width increase with increasing cylinder inclination and number of cylinder. The mean velocity defect profiles collapse fairly well onto each other for all cases. Unlike the aligned cylinders, the wake half-width values for the inclined cylinders decrease first, and then increase thereafter.

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
