摘要/Abstract

摘要： 用带有虚拟流体(Ghost Fluid)修正的Level Set方法计算了一维可压缩双介质流动,把描述流动的Euler方程和描述流体界面运动的Level Set方程耦合起来,得到一个整体的守恒律系统,应用高分辨率差分格式求解;为了解决流体界面附近的数值跳动问题,在界面附近引入了虚拟流体方法的Isobaric修正,并给出了算例.

关键词: 虚拟流体, 双介质可压缩流动, Isobaric修正, 高分辨率差分格式

Abstract: 1-D compressible two component flows are computed with a modified Level Set method where the Euler equations and Level Set equation are combined into a whole conservation law and are solved with high resolution finite difference schemes. In order to minimize the numerical oscillation near the fluid interface, the Ghost Fluid method is used together with the Isobaric Fix, and numerical results are presented for 1-D problems.

Key words: Level Set method, two component compressible flow, Ghost Fluid method with Isobaric Fix, high resolution finite difference scheme
