Abstract
The effect of reduced frequency on the tip vortex in the near field behind a NACA 0015 wing oscillated sinusoidally within the static-stall angle (= 14 deg) was investigated at Re = 1.86 × × 10 5 . The nearly symmetric vortex was observed at 0.5 to 1.5 chords downstream of the trailing edge similar to the case of a stationary wing. The oscillating wing produced a less concentrated vortex of similar diameter and had a larger radial gradient in circulation strength, compared to that of a stationary wing, for reduced frequency less than about 0.1. The axial-flow velocity was always wake-like, with its minimum value increasing with the reduced frequency. The peak value of the vorticity and the vortex strength and the lift-induced drag were higher during pitch-down than during pitch-up. The normalized circulation in the inner part of the axisymmetric vortex also exhibited a self-similar structure, which was insensitive to the reduced frequency. The induced drag increased with the reduced frequency.

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.
