Abstract
This paper concerns modeling of the free surface flow using Volume of Fluid (VOF) method with interface capturing approach. Equation for transport of the volume fraction is discretized using three highresolution schemes. We show that artificial dependence of the high-resolution scheme on the Courant number and switching to first order upwind differencing scheme introduces numerical diffusion that affects solution. Moreover, dynamic character of the scheme can cause artificial interface deformation influencing final wave profile and thus wave drag prediction. Additionally some results connected with modeling of the flow around free surface piercing body are presented.
