報告摘要：This paper focus on the novel mechanism to unify both Lagrangian staggered-grid and cell-centered hydrodynamic methods in one dimension. The mechanism neither contains certain artificial parameters nor solves the Riemann problem. It only includes two key points, one is the relationship between the target cell's pressure and nodal velocity, the other is the Newton's second law. Based on this same mechanism to discretize the corresponding set of equations, both two methods are conservative in total mass, momentum and energy and satisfies the entropy condition. Numerical results show the robustness and the accuracy of both methods.報告人
