Numerical simulation of wave - Moving structure interaction using VOF method

This study is mainly aimed at developing a two-dimensional numerical wave flume based on a VOF method to compute nonlinear interaction between wave and a moving structure. The numerical algorithm developed here is verified by comparing the numerical results with the theoretical ones on the movement distance of bottom-seated and bottom-detached structures in water. The numerical results, furthermore, reveal that the interaction of wave and a moving flap-type structure causes the difference of water levels between the offshore and onshore sides of the structure and has a strong effect on water surface elevation and water particle velocity field around the structure.
