| Abstract: | The drag and flow field around full ships with free-surface were investigated by numerical method.Reynolds average Navier-Stokes equation in conjunction with a RNG k-turbulence model were solved,Volume of Fluid Method(VOF) is devised for the treatment of free surface.The computed results agree well with the conclusions drawn from the published experimental data.It shows that the developed numerical method for viscous flow of full ship with free-surface can satisfy the precision request of the prediction of the powering performance. |
