摘要
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 iso-baric technique is able to significantly reduce the interface overheating problem.关键词
