Abstract

Two one-equation turbulence models proposed recently were applied to Navier-Stokes computations 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 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 reasonably accurate compared with other numerical results. The wake distributions predicted by the present models showed more rounded contours which were improved from the ones by the algebraic model.
