圆盘空化器超空泡流动数值模拟方法

Numeircal Simulation of Supercavitating Flow over Disk Cavitator

为分析来流速度对圆盘空化器产生超空泡的形态,基于粘流理论和有限体积方法,对带有圆盘空化器超空泡航行体流场进行了数值模拟。得到了超空泡形态与航行体速度之间的关系。随着速度的增加,空泡长度逐渐增大。并进一步给出了流场的压力分布云图和速度矢量图。

To analyze the effects on supercavity shape of free stream velocity, the supercavitating flow over disk cavitator was numerical simulated using viscous flow theory and finite volume method. The relationship of supercavity shape and velocity is obtained. The supercavity length is increased as the velocity increasing. The pressure distribution and velocity vector are given as well.
