摘　　要：从可压缩密实介质状态方程出发 ,推导出多介质流体在界面附近满足的动力学方程 ,与守恒律方程一起 ,采用高精度有限体积方法进行求解 ,物质界面用LevelSet函数捕捉。并给出了一维和二维数值算例。A series of dynamic equations applicable for the interfacial vicinity of the multi component compressible material were derived in this paper.Both the equations describing the material interface quality and the conservative Euler equations are incorporated and solved by using a high resolution finite volume scheme.The interface positions are captured by applying level set method independently .Some examples of one and two dimensional are presented.
