CALCULATION OF VISCOUS HYDRODYNAMIC FORCES ON A SHIP HULL IN OBLIQUE MOTION

This paper focuses on computations of viscous hydrodynamic forces acting on a ship in oblique motion by solving thethree-dimensional Reynolds-Averaged Navier-Stokes (RANS) equations. The standard k-ε turbulence model with wall function was applied. The conservation equations were discretized by a cell-centered second-order Finite Volume Method (FVM) in a block-structured body-fitted grid and the couplingof velocity and pressure was resolved withthe SIMPLE method. Computations were performed for a Wigley hull model to investigate the viscous flows around it.The results show good agreement with experimental dataand more reasonable prediction of hydrodynamic forces and moments than other numerical resultsavailable.
