摘要：
Flow around a solid cylinder is numerically simulated with allowance of the movement of the cylinder by the lattice Boltzmann method. The drag force of the fixed cylinder is in good comparison with the literature showing that the fluid force acting on the cylinder is accurately estimated in the computation. It is confirmed that as the body oscillates, the drag and lift forces increases and decreases, respectively. By changing the mooring tension, the locked-in phenomenon and the nonlinear interaction between the vortex-shedding and the mooring system are found.
