摘要
为了研究空化器倾斜角发生变化时流体动力变化规律及其对超空泡航行体控制有效性的影响,对圆盘和圆锥空化器在具有不同倾斜角时进行了数值仿真,仿真结果表明:空化器锥角不同时生成的超空泡形态和空化器的流体动力特性都有很大的不同;不同超空泡航行体对于空化器的选择应该根据航行体自身特点进行选择;将圆盘和圆锥空化器进行组合可以改变单一种类空化器的外形和流体动力特性,增加对空化器选择的灵活性。
In order to study the change law of hydrodynamic force and the influence to the control efficiency of the supercavitating vehicles when the inclination angle of cavitator changed,numerical simulations were carried out for disk and cone cavitators with different inclination angles.The simulation results indicated：The supercavity shape and the hydrodynamic characterics varied with the cone angle of cavitator;the cavitator should be chosen according to its own features of supercavitating vehicle;the combination of disk cavitator and cone cavitator could improve the shape and the hydrodynamic characteristics of a single cavitator and enhance the flexibility of cavitator selection.
