Abstract

The features of a two-phase vapor-droplet flow in a convergent-divergent (Laval) nozzle are studied in the quasi-one-dimensional formulation with allowance for phase transitions. The effect of the governing parameters (the concentration and diameter of dispersed drops, etc.) on the mixture flow was studied in a wide range. The calculations were performed for both subcritical and critical mixture flows. The regularities of a two-phase mixture flow in different critical flow regimes are examined. The effect of governing parameters on the critical (maximum) mixture flow rate is analyzed.

两相汽滴混合物在具有相变的可变截面通道中的流动

摘要

在准一维公式中研究了收敛-发散（拉瓦尔）喷嘴中两相蒸气滴流的特征，并考虑了相变。广泛研究了控制参数（分散液滴的浓度和直径等）对混合物流的影响。对亚临界和临界混合物流量均进行了计算。检查了不同临界流态下两相混合物流的规律性。分析了控制参数对临界（最大）混合物流量的影响。
