Abstract
This paper reports an experimental investigation of the structure of the flow field around finite rectangular cylinder in an open water channel. A particle image velocimetry technique was used to conduct detailed measurements in the streamwise-spanwise plane. The rectangular cylinder with round leading edge of radius 4.5 mm but square trailing edge consists of transparent acrylic plates of nominal thickness, D = 9 mm, length, L = 36 mm (L/D = 4) and height, H = 190 mm. The cylinder was mounted perpendicularly to the channel floor and oriented at four different angles of incidence: θ = 0°, 10°, 20°, and 30°. From these measurements, the iso-contours and profiles of the mean velocities and some turbulent quantities were obtained at various streamwise locations and discussed.

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
