Abstract
目前关于超声速旋流分离器内天然气凝结液化过程的研究较少，为此，通过数值模拟计算对Laval喷管内气体凝结液化过程进行研究，并分析喷管结构对凝结液化的影响。研究结果表明，甲烷气体在喷管内发生了自发凝结现象，但凝结冲波现象并不明显，这与甲烷气体凝结过程液滴生长较慢且凝结潜热较小有关；随着喷管膨胀率的增大，气体过冷度增加越快，其能更早达到凝结液化条件（Wilson点）；喷管内最大成核率、液滴数目及湿度（液化率）均随膨胀率的增大而增大，膨胀率从6 000 s<sup>-1</sup>增大到12 000 s<sup>-1</sup>，成核率最大值增加154.8%，液滴数目增加79.5%，喷管出口湿度增加51.7%，较大程度提高了液化率；对于扩张段长度固定的喷管，过大膨胀率将导致气体温度或压力低于三相点而无法液化；不同膨胀率及不同入口条件下液化率均较低，需进一步开展多级液化研究。

How this classification was reachedexpand
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.
