Abstract :
Experimental and numerical studies were carried out to investigate the viscous hydrodynamic forces acting on a tanker model in oblique motion. Oblique towing tests with a KVLCC2 model were conducted in the towing tank of Shanghai Jiao Tong University(SJTU) in deep water. The lateral forces and yaw moments on the model at different drift angles were measured. The viscous flow around the tanker model in oblique motion was simulated by solving Reynolds-averaged Navier-Stokes equations, and the lateral force, yaw moment, pressure distribution on the hull and the wake were calculated. The experimental and numerical results of the lateral force and yaw moment acting on the hull were compared, and the effect of drift angles on the hydrodynamic forces was analyzed.
