Abstract
Two circular cylinders of equal diameter in a staggered configuration, with a centre-to-centre pitch ratio of PID = 2.0, were tested in the subcritical Reynolds number regime. The incidence angle of the cylinder configuration was varied from a = 0° to 90° and the aerodynamic forces were measured on both the upstream and downstream cylinders. The forces acting upon the upstream cylinder did not show significant variation with the incidence angle despite the marked changes in the vortex shedding behaviour associated with this cylinder. The aerodynamic forces on the downstream cylinder were sensitive to the tendency towards shear layer reattachment at small incidence angles. The inner lift peak for the downstream cylinder, at a = 9°, was attributed to the loss of shear layer reattachment observed at lower incidence angles, while the minimum drag force experienced by the downstream cylinder occurred under shear layer reattachment conditions. Within the range of Reynolds number examined, no apparent Reynolds number effects were noticed.

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
