Abstract
A snowmaking nozzle based on the principle of supersonic speed of Laval nozzle is proposed, and the influence of its operation and structural parameters on flow field and temperature field characteristics is analysed. The results show that the gas-liquid mixture velocity outside the nozzle outlet increases with the increase of air inlet pressure, water inlet pressure and throat diameter, decreases with the increase of distance between water inlet and nozzle outlet. The gas-liquid mixture temperature outside the nozzle outlet increases as water inlet pressure and distance between water inlet and nozzle outlet increases, decreases as air inlet pressure and throat diameter increases. As gas-liquid pressure ratio increases, the gas-liquid mixture velocity outside the nozzle outlet tends to decrease first, then increase and then decrease, while its temperature tends to increase first, then decrease and then increase. When gas-liquid pressure ratio α = 3, this nozzle has the best performance.

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
