摘要

摘要: 为了获得锥形空化器带有翼时受到的流体动力, 通过数值仿真计算, 得到了带不同翼时锥形空化器各部分的流体动力。对计算得到的数据进行了分析, 得到了锥形空化器上翼的阻力和升力随攻角的变化特性, 以及翼的楔角、形状、空化器锥角对流体动力的影响。利用仿真数据验证了在流体动力计算中楔角与攻角之间的等量变换关系。仿真结果表明, 锥形空化器上安装合适尺寸的翼时, 能够有效提高水下航行器的控制力而不增加航行器阻力。

Abstract: To explore the hydrodynamics of a conical cavitator with fins, numerical simulation is performed to obtain the hydrodynamics of a conical cavitator with different fins. The obtained simulation data are analyzed, and the variations of drag and lift forces on the conical cavitator with the angle of attack, as well as the influences of the wedge angle, shape of fin, and cone angle of cavitator on the hydrodynamics, are achieved. The conversion formula between wedge angle and attack angle is verified with the simulation data. Simulation results show that the conical cavitator with proper fins can improve the control force without increasing the drag to an underwater vehicle.
