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.-
