A CONTRIBUTION TO THE CALCULATION OF TURBULENT FLOWS AROUND SHIP HULLS

A method for computing turbulent flows around ship hulls is presented. The Reynolds-averaged Navier-Stokes equations are discretized by a finite-volume method. Either a Low-Re- turbulence model or a standard - turbulence model with wall functions is used. A nonlinear extension to the eddy viscosity hypothesis is employed. Flows around three ship models at Rn = 5 . 106 and a full scale ship at Rn = 1.2 . 109 are computed neglecting the free surface. The predicted velocity distributions in the propeller plane are in good agreement with experimental results. Computed drag coefficients are overpredicted. An explicit multi-block method is restricted to matching grids at block interfaces.
