Experiment of cavity and trajectory characteristics of oblique water entry of revolution bodies

  • 摘要: 针对回转体低速倾斜入水过程空泡的生成机理和演化特性开展研究。通过不同入水速度和入水角度回转体倾斜入水对比实验,研究了入水速度和入水角度对入水空泡、回转体速度、俯仰角及阻力系数的影响规律。研究结果表明:空泡深闭合时刻的空泡长度、最大空泡直径和空泡闭合点深度随着回转体入水速度的增加而增大;空泡深闭合发生时间随着入水速度的增加而小幅增大;同一入水时刻回转体俯仰角和俯仰角速度均随入水速度的增加而减小;随着回转体入水角度的增加,同一时刻入水空泡直径和回转体速度逐渐减小,阻力系数逐渐增大。
