中文摘要：

采用RKDG有限元方法、Level Set方法和改进的带“Isentropic”修正的Ghost Fluid方法模拟了一维多介质可压缩Euler方程，其中Euler方程、Level Set方程和重新初始化方程都采用了三阶精度的RKDG有限元方法进行离散，并对一维两种介质可压缩流体进行了数值实验，得到了较高分辨率的计算结果．

英文摘要：

The RKDG finite element method, Level Set method and modified Ghost Fluid method with Isentropic fix are used to simulate a one-dimensional compressible multicomponent Euler equation. A third-order accurate RKDG finite element method is used to solve the Euler equation, the Level Set equation and the re-initiation equation. Numerical tests on one-dimensional compressible two-fluid flows are made and satisfactory results are obtained.
