摘要: 应用Lagrange坐标系下的守恒型格式计算多介质流体力学问题,在物质交界面附近采用一阶格式的数值通量,而在其余部分采用高分辨率格式的数值通量,不仅保持了高分辨率的良好性质,而且消除了一般的守恒型格式在界面附近所产生的震荡.

Abstract: Conservative scheme in Lagrangian coordination is applied to compute multicomponent fluid dynamics, in which numerical flux of one order scheme is used near interface, while numerical flux of high resolution scheme is adopted in other areas. This scheme not only remains good high resolution, but also eliminates the oscillations due to common conservative scheme.

Key words: multicomponent, conservative scheme, high resolution, Lagrangian coordinate
