摘要
应用RKDG(Runge-Kutta Discontinuous Galerkin)有限元方法、Level Set方法和Ghost Fluid方法数值模拟二维多介质可压缩流,其中Euler方程组、Level Set方程和重新初始化方程的空间离散采用DG(DiscontinuousGalerkin)有限元方法,时间离散采用Runge-Kutta方法.对二维的气-气和气-液两相流进行了数值计算,得到了分辨率较高的计算结果.
The RKDG （Runge-Kutta Discontinuous Galerkin） finite element method, the Level Set method and the Ghost Fluid method are applied to compressihle multimedia fluids. We diseretlzes Euler equations, the Level Set equation and the re-initiallzation equation by a DG （Discontinuous Galerkin） method in space and by a Runge-Kutta method in time. Two dimensional compressible two-fluid flows such as airair, air-liquid are computed. High resolution ratio computational results are obtained.
