【摘要】 本文应用Level Set方法追踪自由面.用二阶投影法和高阶迎风格式求解二维Navier-Stokes方程,用立方插值拟质点方法求解Level Set方程.对气泡在水中这一运动过程进行了数值模拟,可得到各个时刻气泡运动界面的变化和相应速度的分布.本文的数值结果与文献[7]的的实验结果基本吻合,说明本文的算法实用且有效.
【Abstract】 in this paper the Level Set method is introduced to simulate the flow of dambreak. The second order project method and high order difference scheme is used to solve the two-dimensional Navier-Stokes equations, and CIP(Cubic-Interpolated Pseudoparticle) method is adopted to solve the Level Set equation. Our experiments simulate the flow of air bubbles in the water. The evolution of the moving interface and the contour of the velocity are given. The numerical results are shown to be in good agreement with experimental results by reference [7], and to demonstrate the effectiveness of this method.
