WAVE FORCES ACTING ON A BLUNT SHIP WITH FORWARD SPEED IN OBLIQUE SEAS (4TH REPORT)

In a previous report a new numerical approach based on the 3- D panel method was presented for the estimation of the wave forces acting on a half-immersed spheroid advancing in oblique short waves. This numerical approach consisted of the spline approximation of the ship surface and the velocity potential distribution on it, and the integral equation directly with respect to the velocity potential itself. It was clear that this method improved the predicted results of the wave forces on the spheroid in oblique short waves. In this paper, the numerical approach is applied to estimate the wave forces and the pressure distribution on a realistic blunt ship advancing in oblique short waves. The steady disturbance on a realistic blunt ship surface was taken into account. The numerical results of the method are compared with experimental results and numerical results obtained by the strip method. The results are in good agreement with the experimental results of radiation forces and pressure distributions on the ship surface.
