Analysis of tail-slaps of supercavitating vehicle influenced by distortion of cavity shape

  • 摘要: 针对超空泡航行体存在尾拍运动与空泡形态变化互相耦合作用的特点,建立了超空泡航行体尾拍耦合运动方程,并对超空泡摆动对超空泡航行体尾拍相互作用过程进行了数值研究,对比分析了不同速度和角速度的超空泡航行体运动过程及空泡摆动对尾拍的影响规律.研究结果表明:空泡摆动使航行体转角、整体运动周期、尾拍升力和阻力增大;在不同速度下,空泡摆动对航行体转角、整体运动周期及尾拍周期的影响随速度增大而逐渐减小;不同初始角速度下,空泡摆动对航行体转角、整体运动周期、航行体尾拍升力和阻力的影响随角速度增大而逐渐增大.
