AN EXPERIMENTAL STUDY ON DIRECTIONAL RESISTANCE PROPERTIES OF A SUBMERGED ASYMMETRICAL ROUGHNESS
Bibliographic record
Abstract
Directional characteristics of hydrodynamic force on a submerged asymmetrical roughness (we call this roughness BaNK block) in oscillatory flows were experimentally investigated. In this study, a quarter sphere or a half cylinder is used as a BaNK block which is set on the bottom of channel with an angle of attack θ to an oscillating flow direction. It is found that residual hydrodynamic force on half cylinder is much larger than that on quarter sphere because the substantial length of quarter sphere is smaller than that of half cylinder. Furthermore, residual hydrodynamic force on BaNK blocks is almost constant with the change of θ when Keulegan-Carpenter number KC is small. However, in large KC number, the force on quarter sphere decreases with the increase of θ because residual lift force decreases in θ=50°-90°.

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.
