Effect of dynamic wind direction changes on aerodynamics of a square inclined flat plate in ground effect
Bibliographic record
Abstract
View Video Presentation: https://doi.org/10.2514/6.2023-3676.vid The aerodynamics of a square inclined flat plate is investigated for yaw angles between 0° and 30° at a ground clearance of 0.1 chord length. The chord Reynolds number is 50000 and the angle of attack is 30°. Direct lift measurements are collected using a load cell and three-component planar particle image velocimetry is used to capture tip vortex development. Transient change in wind direction is modeled by a yaw rotation from 0° to 30° as well as from 30° to 0°, over 3.8 convective time units. Notable hysteresis is observed in the lift coefficient between the two rotation directions, which is found to originate from differences in tip vortex development. The lift coefficient is found to exhibit a mild overshoot of 10% compared to steady state values, providing guidance for support structure design and load control strategies in transient wind direction changes.

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.
