摘要/Abstract

摘要： 为研究水下垂直发射航行体尾空泡的瞬态振荡演化特性，及其对航行体流体动力、航行体上游流动的影响，基于势流边界元，提出了附着尾空泡航行体流场的瞬态计算方法。通过对垂直向水面运动的尾空泡瞬态振荡过程开展数值计算，分析尾空泡振荡对上游物面压力、沾湿区阻力以及空泡发展3方面的影响规律。结果表明：尾空泡振荡会引起上游物面压力在随环境静压下降的同时叠加一定幅值的压力波动，压力波动在空间上呈近似指数分布，越接近尾空泡的位置，压力波动越大；尾空泡振荡使得航行体沾湿区的阻力呈现在振荡中逐渐增大的变化趋势；尾空泡的振荡会导致肩空泡发展速度相比无振荡状态减缓，同时泡内压力和末端回射压力峰值偏大。

Abstract: In order to investigate the evolution characteristic of tail cavity formed by underwater vertical launch vehicle, as well as the influence of tail cavity on the hydrodynamics and upstream flow of the vehicle, an axisymmetric boundary element code based on potential flow theory was developed to analyze the transient flow field of vehicle with tail cavity. A numerical simulation was performed. The simulated results show that the oscillation of tail cavity has a significant influence on the upstream pressure, the drag force on wet surface and the upstream nose cavity. The oscillation of tail cavity can cause the upstream surface pressure to superimpose a certain amplitude of pressure fluctuations while dropping with the environmental static pressure. The pressure fluctuations are approximately exponentially distributed in space. The closer the position is from the tail cavitation, the greater the pressure fluctuation is. The oscillation of tail cavity makes the resistance of the wetted area of the vehicle show a trend of gradual increase during the oscillation; the oscillation of tail cavity can cause a slower evolution speed of shoulder cavity than that in the non-oscillation state, and the pressure inside the cavity and the peak end retroreflective pressure are larger.
