| Abstract: |
| It is found that the original ghost fluid method does not work well when applied to strong shock impacting on material interface. While modified ghost method can handle this kind of problems well. In this work, the position of material interfaces were captured by Level set, the parameter of ghost points were defined by MGFM, and HLLC was applied to solve Euler equations. Numerical results of 1-d and 2-d cases show that MGFM was applied successfully in strong shock impacting on material interface. |
