Flows around two full hull forms in oblique towing or steady turning motion have been computed using a CFD code NICE with the Baldwin-Lomax turbulence model. The computed flow in oblique towing agreed well with experiments in terms of the sway force distribution in the longitudinal direction, as well as the integrated sway force and yaw moment, and the computed hull surface pressure distribution explained well the difference in the sway force distribution on two hull forms. The modified Baldwin-Lomax model gave better results than the original model. Using the same code, flows in steady turning were also computed. Although the agreement with experiments were slightly less satisfactory than those in oblique towing, the modified turbulence model gave better results again.
