Numerical simulation of impact loads using a particle method Academic Article uri icon


  • The violent free-surface motions interacting with structures are investigated using the moving particle semi-implicit (MPS) method, which was originally proposed by Koshizuka and Oka (1996) for incompressible flow simulation. In the present numerical method, a more efficient algorithm for Lagrangian moving particles is used for solving various highly nonlinear free-surface problems without using the Eulerian approach or the grid system. Therefore, the convection terms and time derivatives in the Navier-Stokes equation can be calculated more directly without any numerical diffusion, instabilities, or topological failure. In particular, the MPS method is applied to the simulation of liquid-entry and slamming problems, such as wet-drop (liquid-liquid collision) tests in an LNG tank and slamming loads (solid-liquid collision) on rigid plates with various incident angles. The numerical results are in good agreement with available experimental data. 2009 Elsevier Ltd.
