Abstract

This chapter introduces numerical computation methods recently developed at RIAM (Research Institute for Applied Mechanics), Kyushu University, for strongly nonlinear wave-body interaction problems, such as ship motions in large-amplitude waves, resulting green-water impact on deck, and so on. Introduced first is the CIP-based Cartesian grid method, in which the wave-body interaction is treated as a multiphase flow with liquid, gas, and solid phases. Development of an efficient interface-capturing scheme is a key and a couple of new conservative schemes are tested. Introduced second is the MPS method, which is a so-called particle method and hence no grid is used. The features and calculation procedures of these methods are described some-what at length, and their validation is performed through comparisons with some experiments conducted at RIAM.
