【英文论文摘要】 In the paper,the drag and flow field around bulk carrier with free-surface were investigated by numerical method.Reynolds average Navier-Stokes equation in conjunction with a RNG k-ε turbulence model were solved,Volume of Fluid Method(VOF)is devised for the treatment of free surface.The computed results agree well with experimental data.It shows that the numerical method of bulk carrier with free-surface can satisfy the precision request of the prediction of the powering performance.
