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。Abstract: 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.
