摘要

摘要: 尾部喷流与超空化流场的相互影响涉及空化流动以及带相变的复杂多相流问题,就目前的条件而言，采用数值仿真方法难度很大,试验研究成为主要研究手段。针对如何在水洞开展尾部喷流对超空化流动影响试验，提出了研究超空泡航行体尾部喷流的试验方法, 推导了一个新的相似准则数，为确定研究尾部喷流的试验参数提供了依据。利用商用软件Fluent，对水洞模型试验的支撑方式进行了数值仿真，结果表明，头支撑方式对模型超空化流场影响较小，更适合尾喷问题的试验研究。水洞模型试验验证了数值仿真结果的正确性。

Abstract: We investigate an experimental method for analyzing the influence of tail jet on the ventilated supercavitation flow field of underwater vehicle. A similarity criterion for water tunnel experiment of tail jet is derived, which can help to set parameters of tail jet intensity. Numerical simulations of support mode to model are performed, and the results indicate that the head support mode is more suitable than the abdominal mode for this experiment. Water tunnel tests verify the reasonableness of the previous numerical simulations. Therefore, experimental study method about tail jet of supercavitating vehicle is understood.
