摘要：

A new method is presented for the water impact simulation,in which the air-water two phase flow is solved using the pressure-based computational fluid dynamics method.Theoretically,the air effects can be taken into account in the water structure interaction.The key point of this method is the air-water interface capture,which is treated as a physical discontinuity and can be captured by a well-designed high order scheme.According to a normalized variable diagram,a high order discrete scheme on unstructured grids is realised,so a numerical method for the free surface flow on a fixed grid can be established.This method is implemented using an in-house code,the General Transport Equation Analyzer,which is an unstructured grid finite volume solver.The method is verified with the wedge water and structure interaction problem.
