NUMERICAL SIMULATION OF FLOWS AROUND KVLCC2 HULL FORM WITH SHIP MOTIONS IN REGULAR WAVES

Unsteady RANS simulations of flows around a tanker hull form with ship motions in regular waves are carried out. The results of Fourier analysis are similar with the measured results and within the deviation of the results in the workshop. From the analysis of the flows on the propeller plane, the incresing of time averaged nominal coefficient can be derived from the forward speed diffraction case in short wave length. In long wave length, the vortices on the propeller plane are induced by the ship motions and increase of time averaged nominal wake coefficient is affected by the interaction between waves and ship motions, the effect of forward speed diffraction case and forced heave motion are in same order.
