Abstract

A method of computational fluid dynamics is investigated for numerical simulations of strongly nonlinear phenomena with the large deformation of the free surface. The numerical solution method of this study is based on the CIP (Constrained Interpolation Profile) scheme, and the multigrid technique for solving a pressure Poisson's equation with high efficiency and robustness. The method developed was applied to dam breaking and sloshing in a tank. As a result, the numerical computations confirmed that the method developed provides fairly efficient and robust computations in 3-dimensional simulations of violent free-surface flows involving strong water impacts.
