  In this paper,an improved SPH model for multiphase flows with complex interfaces and large density differences is developed.The multiphase SPH model is based on the assumption of pressure continuity over the interfaces and avoids directly using the information of neighboring particles densities or masses in solving governing equations.In order to improve computational accuracy and to obtain smooth pressure fields,a corrected density re-initialization is applied.
