VISCOUS FLOW COMPUTATIONS AROUND A SHIP USING ONE-EQUATION TURBULENCE MODELS

Two one-equation turbulence models recently proposed were applied to Navier-Stokes computation of viscous flows around ship hulls. The turbulence models consist of a single advection/diffusion equation for eddy viscosity. Flows around two tanker models, the HSVA tanker and the Dyne tanker, as well as a flat plate were computed with these turbulence models. Results were compared with measured data and the computations with the conventional algebraic turbulence model. Resistance values computed with the one-equation models were found to be reasonable accurate compared with other numerical results. The wake distributions predicted by the models showed more rounded contours which were an improvement on the contours predicted by the algebraic model.
