Computation of hydrodynamic characteristics of ships using CFD

This paper investigates various hydrodynamic characteristics of two conventional ships namely Wigley hull and Series 60 ship by commercial CFD software named Shipflow. Zonal approach is applied to incorporate ‘potential flow solver’in the region outside the boundary layer and wake,‘boundary layer solver’in thin boundary layer region near the hull and ‘Navier Stokes solver’in the wake region successively. Finally free-surface wave pattern, wave elevation, pressure coefficient on hull, boundary layer streamline and different resistance components at different speeds are computed and validated by comparing with experimental results.
