In recent years, the utilization of computational fluid dynamics (CFD) in various industrial fields has broadened following developments in computer technology. Although mainstream CFD is currently based on a grid method in an Eulerian framework, it is difficult to apply this to the simulation of problems in which large deformations of interfaces between phases occur. For this reason, particle methods are now receiving attention. In this study, we developed a numerical method to couple the particle and grid methods in order to simulate a gas-liquid two-phase flow. We conducted numerical tests on present numerical method with an impingement-jet to the liquid surface and the results show reasonable agreement with the experimental data. Thus, we confirmed that our numerical method can reproduce gas-liquid two-phase flow including interactions between different phases without being affected by the numerical diffusion and instabilities.
