【Abstract】 This paper presents a formulation for the new front-capturing method, i.e., the level set method, and some results of this method when applied in numerical simulation of interfacial waves on a planar interface of two immiscible fluids. It is showed that the level set formulation can successfully capture the main behavior of the interfacial waves, and the numerical results are in very good agreement with experimental results and observations. Results of this paper indicate that the method thus employed is a very promising method for two-phase flow simulation and deserves further study and development.更多还原
