MPS-FEM数值分析带自由面的流固耦合问题
Simulation of fluid-structure interaction with violent free surface by MPS-FEM coupled method
摘要
Abstract
With the development of computational science,various kinds of numerical methods are proposed for the analysis of fluid-structure interaction problems.Recently,a coupled Moving Particle Semi-implicit(MPS) method and Finite Element Method(FEM) is developed as a new approach for FSI problems.In the present study,simulation of fluid fields is carried out by the mesh-free method solver MLParticle-SJTU.The solver is implemented based on the MPS method with improvements on the kernel function,free surface detection,gradient model and Possion''s equation of pressure.Furthermore,the module for calculation of structural deformation is developed base on the FEM in the framework of MLParticle-SJTU.In this paper,both MPS and FEM are introduced firstly.Then,the benchmark of the interact between the dam-break flow and the elastic structure is numerically investigated with the help of the presented MPS-FEM coupled solver.Deformation of the elastic structure and evolution of the violent free surface are found to be in good agreement with published results,which shows that the proposed MPS-FEM coupled method is capable of dealing with structural deformation interacting with violent free surface flow.关键词
