回射流 meaning in Chinese

reentrant jet

The main work in this paper includes three parts : the theory research on partially - cavitating and super - cavitating axisymmetric bodies , the numerical computations and experimental investigations on partially - cavitation and super - cavitation on axisymmetric bodies . after finishing the study of theory and experiment on the partially - cavitation and super - cavitation for axisymmetric body , i use the potential flow theory to build the mathematical model on the partially - cavitation and super - cavitation for axisymmetric body . many cavity wake models , such as pressure recovery close model , riabouchinsky model and re - entrant jet model , are studied seriously
本文在深入研究了回转体局部空化与超空化理论及实验结果的基础上，基于势流理论，建立了回转体局部空泡和超空泡流场的基本数学模型，通过对kinnas和fine 、 uhlman以及jiedang和gertkuiper等人基于二维水翼提出的压力恢复闭合模型、镜像板模型和回射流模型等空泡尾流模型进行了逐一的研究分析，发现其中的压力恢复闭合模型较适用于模拟回转体空泡尾部流场，并选用此空泡尾流模型作为求解回转体空化流场正问题与逆问题的数学模型的组成部分。
