| Abstract: | In this paper,we extend a two-dimension code,which couples an Eulerian program(SCB scheme) with a Lagrangian code(DEFEL: 2-D finite element code),to the context of multi-interface scenario by developing a Ghost-fluid Euler-Lagrange(GEL) coupling method.We use water-air one-dimension dual interfaces Riemman problem as a case study to evaluate the proposed method.The density,velocity and pressure distributing are acquired.And the experiment results show that the isobaric technique is able to significantly reduce the interface overheating problem. |
