摘要：To utilize floating structure under heavy environmental condition in sea safely, motions of the floating body and the mooring forces acting on the body have to be reduced. To decrease these motions and mooring forces, fins attached structure has been proposed.In this paper, as a first step of the study, two vortex methods, the Random-Walk method and the Core-Spreading method, are applied to uniform flow past a circular cylinder and heaving fin plate under free surface. In the simulation of uniform flow, we conduct parametric study which helped us determine the numerical parameters to be used in subsequent simulations. Then, the simulated wake velocities are compared with experimental results to verify the calculation accuracy. In the simulation of heaving plate, hydrodynamic forces on the plate are simulated and compared with experimental results.
