Open Channel Flow over Rectangular Cylinders at Incidence
Bibliographic record
Abstract
This paper reports a study of turbulent wake of two-dimensional rectangular cylinders in an open channel. The water depth upstream of the cylinders was maintained at 100 mm. Three cylinders having aspect ratios (defined as the ratio of the cylinder’s length to thickness) of 1, 2 and 4 were mounted vertically at mid-span of the open channel. For each aspect ratio, the cylinders were oriented through four angles of incidence (0°, 15°, 30° and 45°). A particle image velocimetry technique was used to conduct detailed velocity measurements at various streamwise-spanwise planes around the cylinders. From these measurements, the mean streamlines, iso-contours of turbulence kinetic energy and Reynolds shear stresses as well as the profiles of the mean velocities and turbulent quantities were obtained to document the effects of cylinder aspect ratio and angles of incidence on the wake characteristics.

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.
