摘　　要：航行体尾部附着空泡振荡会影响航行体的受力和运动状态,本文建立势流边界元空泡流数值计算方法,通过与已有试验数据对比,验证计算方法的有效性,并在此基础上对不同尾部外形航行体尾空泡流场进行计算分析。针对附着空泡相对稳定状态,计算了不同航行体尾部外形下空泡形态变化以及空泡对上游航行体物面压力分布的影响。对于空泡动态演化过程,研究了空泡振荡过程中压力和形态的变化,探究了尾空泡影响上游航行体物面压力变化的主要原因,并分析了不同尾部外形航行体沾湿区阻力的变化情况。The oscillation of cavity attached to underwater vehicle with different tail shape has an influence on the force and motion state of the vehicle,a numerical calculation method for cavity flow based on potential flow boundary element was developed,the effectiveness of the method is verified by comparing with the experimental results,and on this basis,the flow field of tail cavity with different tail shape was calculated.For the steady cavity condition,the change of cavity morphology and the pressure on vehicle was calculated.For the cavity dynamic evolution,the pressure and morphology of cavity was studied,the main reason of the influence on vehicle pressure was explored,and the change of vehicle drag was analyzed with different vehicle tail shape.
