| 摘 要： | 根据Logvinovich独立膨胀原理发展了一种用于非定常通气超空泡形态的计算方法,并运用该方法对通气超空泡形态控制进行了数值仿真.研究表明:调整流场压力、模型速度、空化器阻力系数对超空泡长度的控制范围较大,响应速度较快;调整通气量对超空泡长度控制范围较小,响应速度较慢;此外改变超空泡内部模型的尺度和结构也可以对通气超空泡形态进行控制.

| Abstract: | a numerical strategy was brought forward to evaluate and simulate unsteady ventilated supercavitation based on the Logvinovich principle of cavity sections expansion. The results indicates the wide control range and high response speed of supercavitation length as adiusting flows pressure, model velocity and cavitator drag coefficient, or the narrow control range and low response speed as adjusting the air-supply rate. In addition, the model dimensions and structure can also be used to control supercavitation shape. |

| Keywords: | ventilated supercavitation the principle of Logvinovich of the cavity sections expansion control method of supercavitation unsteady numerical simulation |
