Abstract
This paper presents a systematic investigation of vortex-induced vibration (VIV) of a D-section prism at subcritical Re. It is found that the response is persistently VIV typed, which can be excited and sustained by the viscous and/or pressure lift coefficient. Galloping is found to be absent because it requires an unstable structural mode with a frequency close to the prism natural frequency and flow mode with the natural vortex shedding 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 it
