摘要
为了解hydronautics超空化水翼的绕流流场特性,采用高速摄像机等流动显示设备,在空化水洞中针对此种超空化水翼进行了一系列绕流流场显示实验。实验结果表明,绕这种超空化水翼的空化形成与发展,均与产生于翼型前端 (吸力面)和尾端(压力面)的旋涡或二者的结合体:空化涡街有关;空化数的大小,决定了空化涡街形成与溃灭的不同特征;当空化数较低时,涡街中空化旋涡的扩张形成了闭合的超空化区域。
The cavitating vortices around a hydronautics supercavitation foil have been observed by means of a high-speed video camera. The results show that the forming and developing of cavitation around the hydrofoil are related to the vortices produced at the foil＇s front （suction side） and rear （pressure side）, or the combination of both ： vortex street; the characteristics of the cavitating vortex street＇s forming and crumbling depend on the variation of the cavitation number; with the decreasing of cavitation number, an enclosured supercavitating area will be formed with the expanding of cavitation vortices among the vortex street.
