| Research Abstract |
The object of this research is development of the numerical method to evaluate the wave-making resistance taking into consideration the nonlinear and viscous effects.
1. The group of University of Tokyo developed the computer codes to obtain the flow fields around the ship hull using the viscous model and the body-fitted coordinate system and the finite difference method. They calculated the flow fields around the Wigley hull at Reynolds Number <10^4> .
2. The group of Hiroshima University developed the computer code to obtain the flow fields under the effects of nonlinearity and viscosity using the boundary element method. They calculated the flow field around the elliplic body by solving the vorticity transport equations.
3. The group of Kyushu University developed the computer code to obtain the flow fields under the nonlinear effect using the boundary element method. They calculated the flow fields around the lens-shaped ship, Wigley hull and Series-60 hull and confirmed the validity of this method in the sense of practical usage.
