The numerical simulation of free surface flow around Frigate Model 5415 was carried out by solving Reynolds Averaged Navier- Stokes equations (RANSE) and RNG K- ε two- equation turbulence model together with non- equilibrium wall functions. Volume of Fluid (VOF) algorithm with Geo- Reconstruct scheme was applied.QUICK difference scheme for convection was used.Computational results including resistance,wave profile and wake distribution were compared with experimental data.
