Study on Drag Reduction Characteristic Around Bodies of Revolution with Bionic Non-smooth Surface
Bibliographic record
Abstract
Bionic non-smooth structures on the bodies of revolution had characteristic of drag reduction. In this paper, oil flow visualization test were made in low speed wind tunnel between two bionic non-smooth surface models and smooth surface model. The results show that the oil flow pattern is significantly difference according to the configuration of non-smooth structures, and had obviously effect on the friction of the model. However, the total drag coefficient of BNNS model is reduced. It was found that the BNSS can decrease the pressure drag obviously. The mechanism of BNSS is through sacrifice small viscous force, early flow separation on the blunt body of revolution was restrained, and the pressure force reduced dramatically, so the total force reduced also. Key words: Oil flow visualization; drag reduction; non-smooth surface; bionic

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.
