Abstract
The nonlinear ship-wave interaction phenomenon occurring when the relative free surface motions exceed the free board of a vessel is studied using RANSE based Computational Fluid Dynamics. Present work illustrates a methodology developed using an unsteady RANSE based CFD tools to simulate complex green water flows and determine rate of water ingress into open holds of container ship. The methodology involves modeling appendages, open holds and generation of irregular waves. Simulations are performed on an open top container vessel operating in long crested irregular seas for one case as specified in the model test procedures given by IMO. Numerical computations of motion responses and rate of water ingress are compared with experiments.
