NAVIER-STOKES COMPUTATIONS OF SHIP STERN FLOWS: A DETAILED COMPARATIVE STUDY OF TURBULENCE MODELS AND DISCRETIZATION SCHEMES

A fully elliptic numerical method for the solution of the Reynolds Averaged Navier Stokes Equations is applied to the flow around the HSVA tanker. The weaknesses of the simulation are analyzed by comparing several discretisation schemes and grids as well as several turbulence models. Grid refinement in the near wake or application of new accurate discretisation schemes have a little effect on the quality of the solution in the wake. Systematic comparisons of various turbulence models and numerical experiments suggests that the solution is essentially affected by a too high level of turbulence viscosity in the core of the longitudinal vortex.
