Abstract
A conventional way of studying the flow characteristics of flow over a bluff body is by extracting the velocity distribution in horizontal planes crossing the bluff body near the bed, mid-height and close to the free-end location.The intention of selecting the planes at these levels is to examine the horseshoe vortex and the bed effect, flow separation at the mid-height, and the downwash flow from the free-end.In some cases, where a relatively short cylinder is studied along with a taller cylinder, the mid-height level of each may present very different flow structures.It is proposed in this study that a better way of selecting the planes of interest could be based on the pressure distribution imposed on the front surface of the bluff body by the approaching flow.This paper uses a sample numerical study of wall-mounted finitelength square cylinder with three aspect ratios of 1, 2 and 4, immersed in the air flow with a thin boundary layer.The horizontal planes based on the front face pressure distribution are selected and examined to show the advantage of the proposed method.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
