Numerical simulation of multiphase flow field and trajectory of high-speed oblique water entry of rotating projectile

  • 摘要: 基于VOF多相流模型和有限体积法求解水、汽、气多相流动的RANS方程,结合重叠网格技术和six DOF算法对某一型号舰载射弹倾斜入水过程进行数值模拟研究。首先基于该方法研究了射弹旋转效应对射弹运动特性及流体动力特性的影响,然后对不同入水角下倾斜入水过程进行分析,得到不同倾角下旋转射弹入水空泡形态发展规律、弹体运动特征及流体动力特性变化规律。研究结果表明:射弹的旋转有利于弹体在初始对称面内的弹道稳定性,但会降低弹体侧向稳定性,使射弹受到的阻力系数、俯仰力矩系数变小;入水角越小,形成的空泡越不对称,由射弹运动状态的改变引起的空泡形态变化越明显,在超空泡航行阶段,弹体运动较稳定,不同角度下流体动力系数差别很小,当弹体下表面刺破空泡壁沾湿时,弹体运动状态发生较大变化,流体动力系数迅速增大,此时入水角度过小,弹体容易失稳;弹体的沾湿对空泡形态、弹体运动稳定性和流体动力特性有着重要的影响。
