摘要

摘要: 针对气泡在舰船尾迹涡流场运动特性，根据其是否为尾涡所捕获，将数值模拟过程分为两个阶段：准球状运动阶段和非球状运动阶段．分别应用单向耦合质点粒子追踪法（PTM）和边界元法（BEM）模拟这两个阶段，将第1阶段结束的物理量作为第2阶段的初始条件，从而完成整个数值模拟过程．在已有数值研究结果和实验数据基础上，探讨空化发生条件，追踪尾迹空泡运动轨迹，模拟尾迹气泡的运动、变形、溃灭等，以及被尾涡捕获后的撕裂等运动特性，旨在为优化设计尾流场提供参考．

Abstract: According to the behavior of a bubble in the ship wake flow, the numerical simulation was divided into two stages: quasi-spherical motion and non-spherical motion, based on whether the bubble was captured by the vortex or not. Oneway coupled particle tracking method (PTM) and boundary element method (BEM) were adopted to simulate these two stages respectively. Meanwhile, the initial condition of the second stage was taken as the output of the first one and the whole simulation was connected and completed therefore. Based on the numerical results and experimental data published, the cavitation inception was studied and the wake bubble was tracked. Besides, the split of the bubble captured by the vortex and the following sub-bubbles were simulated, including the motion, deformation and collapse as well. It is aimed that the results would provide some insight into the control on wake bubbles and optimization of the wake flow.

- tip vortex /
