The numerical simulation of free surface flow around Series- 60 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. Power- law, second- order upwinding and QUICK difference schemes for convection were used.Computational results including resistance,wave profile and wake distribution were compared with experimental data in detail.The comparison shows that this computational method has the advantage of high accuracy for engineering purpose.
