摘要

摘要本文研究了全润湿和部分润湿对空化现象的影响。为了对拉瓦尔喷嘴内的流动进行数值计算，测试了Schnerr-Sauer空化模型，并将其用于考虑局部表面润湿的喷嘴内流动的空化研究。采用部分表面润湿引起的流体流动的实验、理论和数值方法，确定了各种材料的润湿系数。

The Investigation of the Cavitation Phenomenon in the Laval Nozzle with Full and Partial Surface Wetting

Abstract The article deals with the cavitation phenomenon affected by full and partial wetting of the wall. For the numerical computation of flow in the Laval nozzle the Schnerr-Sauer cavitation model was tested and was used for cavitation research of flow within the nozzle considering partial surface wetting. The coefficient of wetting for various materials was determined using experimental, theoretical and numerical methods of fluid flow due to partial surface wetting.
