| The RKDG finite element method. Level Set method and Ghost Fluid method are applied to simulate compressible multimedia fluid in this paper. It is realized by RKDG finite element method to trace the moving interface. The two dimensional constant flow, rotating flow and shear flow have been traced. The one-dimension Ghost Fluid method is modified. A new Ghost Fluid method with Isentropic fix is given so that it can simulate the hydrodynamics problem with multimedia high density ratio. Some numerical tests show the high resolution ratio results on one dimensional and two dimensional compressible two-fluid flows such as air-air, air-liquid. |
