摘要：

In this paper, a multiphase Godunov-type smoothed-particle hydrodynamics (MGSPH) method is presented for simulating multi-fluid Riemann problems with complex equations of state (EOSs). In this method, single-phase Riemann solvers are used between particles with same phase, and interfacial approximate Riemann solvers are introduced on the interfacial particle pairs. Various combinations of single-phase and interface approximate Riemann solvers are comparatively studied to find out the best combination for MGSPH. Five examples are presented to verify MGSPH method.
