Abstract
The objective of this study is to investigate the decreasing ambient pressure at nozzle exit. If there is a sudden expansion section in supersonic ow at the Laval nozzle exit, phenomenon of decreasing pressure will occur at the downstream. Using this phenomenon to decrease the ambient pressure, the cover that can expand the tube area is placed at nozzle exit. Mach number of ow through the inside of nozzle and cover increase as the ratio of stagnation pressure and ambient pressure rise up. In this paper, we present the results obtained from numerical analysis of ow expansion and increasing of Mach number by the cover and the decrease of the pressure at nozzle because of the difference in pressure ratio.

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
