2D SIMULATION OF a FREE-FLOATING S TRUCTURE MOTIONS IN WAVES OF a FLAPPING-TYPE WAVEMAKER abstract
A numerical model to simulate motions of a free-floating structure in a wave tank is proposed based on finite volume discretisation. This is developed by implementing an overlapping meshsystem consisting of three meshes. Two of them follow wavemaker's paddle forced motions as well as structure's free motions in waves. The last one which is a fixed mesh also covers the whole domain while it is responsible for meshes inter connections. By simulating a flapping-typewavemaker and recording three degrees of freedom of motions of a structure in front the generated waves using developed software, it is now obvious that the algorithm is capable of simulating other wavemakers as well as different hydrodynamic aspects of such problems
