Numerical simulation of high-speed water-entry cavity of cone cylinder

  • 摘要: 采用流体体积法(VOF,Volume of Fluid)多相流模型,引入动网格技术,对锥头圆柱体垂直自由高速入水问题开展了数值模拟研究,分析了航行体入水后速度及入水空泡形态的发展规律,并与文献基于能量守恒定律的理论结果进行比较,两者吻合较好.研究结果表明,高速入水初期,结构受到极高的冲击载荷,导致速度迅速衰减;随着入水深度的增加,空泡不断拉长并向径向扩张,空泡内空化现象明显,空泡内混合相对空泡壁及空泡分离点附近压力分布影响显著.对于不同速度入水的研究结果表明,入水速度越高,航行体头部压力峰值越大,相同时刻入水空泡最大直径也越大.
