摘要

摘要: 用非耦合求解方法计算Level Set函数方程与流体力学方程组，应用重新初始化的Level Set函数确保距离函数性质，流体力学方程组采用二阶精度多介质流波传播差分格式计算，重新初始化方程采用五阶WENO格式计算。并给出了二维可压缩多介质流界面运动的计算结果。

Abstract: We applied re-initialized level set method for enforcing level set function to preserve distancing character. Level set equation and fluid dynamic Euler equations were solved independently. Multi-fluid wave propagation method for fluid dynamic Euler equations and fifth order WENO scheme for re-initialization level set equation were used. Some comparable results for 2D compressible multi-fluid interface problems are given.
