Oscillating-Wing Tip Vortex with Passive Short-Span Trailing-Edge Flaps
Bibliographic record
Abstract
Tip vortex flow behind an oscillating NACA 0015 wing with passive short-span trailing-edge flaps was investigated experimentally at Re = 1.81 x 105. The spoiler was found to be very effective in diffusing the tip vortex, in terms of the reduction of peak tangential velocity ν θpeak and vortex strength, compared to a baseline wing, and also led to additional vertical upward displacement of the vortex center. No significant influence on the vortex size was observed, however. The spoiler-induced negative camber effects also translated into slightly reduced bound circulation, total lift, and lift-induced drag. For a tab, the dynamic increase-decrease in the vortex size and strength persisted and had values larger than for a baseline wing. No substantial change in ν θpeak , compared to that for a baseline wing, was noticed. The axial core velocity was always wakelike, and the vortex center was shifted relatively outboard and vertically downward below the baseline wing. The tab also led to an increase in the lift and drag forces. The symmetric flap provided a compromise in the critical vortex-flow quantities between the spoiler and tab cases.

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.
