@@@@CFD prediction of powering performance for a surface ship model KCS is carried out in this paper. Numerical computation of resistance for the ship model is performed firstly. Open water performance for propeller model KP505 is computed then. Numerical tests of self-propulsion of the ship model are carried out thirdly. Self-propulsion parameters are obtained through analyzing the results of CFD simulation. Powering performance of the full scale ship is predicted finally. It is shown that the results of numerical simulation and analysis agree quite well with the experimental results.
