Abstract

A two-dimensional time-domain coupled numerical model is developed in order to obtain efficient method for nonlinear wave forces acted on moored ship in harbor.The fluid domain is divided into an inner domain and an outer domain.The inner domain is the area under the ship section, which is governed by Euler equations.The outer domain is the area outside the two sides of ship hull, which is governed by Boussinesq equations.Matching conditions on the interface boundaries between the inner domain and the outer domain are the continuation of volume flux and the equality of pressures.In addition, the boundary element method in complex is adopted to verify the coupled model.Relevant physical experiment is conducted to validate the two numerical models, and it is shown that the numerical results agree with experimental results, but the computational efficiency of the boundary element method is much lower than that of the coupled model.In addition, the numerical computations of the coupled model are simple, which can be used to compute the nonlinear wave forces acted on moored ship in harbor.
