Effects of operating pressure on high-speed projectile's water-entry flow

  • 摘要: 为研究空气域压力对射弹入水流场的影响,采用流体体积法(VOF)多相流模型对锥头圆柱体高速入水过程进行数值模拟,得到射弹入水速度与入水深度以及空泡形态的分析结果,并将数值模拟结果与基于牛顿第二定律和文献的理论结果进行对比,验证数值方法的正确性.基于该方法针对不同空气域压力条件对入水过程进行分析, 结果表明空气域压力对自由液面上方的喷溅形态、空泡表面闭合时间以及空泡内部空化效应影响较大.空气域压力越大,空泡敞开阶段的空泡口处半径越小,空泡发生表面闭合的时间越早,空泡内部空化效应越强.
