Three-dimensional turbulent flow past a ship hull is studied numerically using Reynolds-averaged Navier-Stokes (RANS) equations. The RANS solver is based on cell-centered finite-volume discretization and segregated solution procedure, permitting use of unstructured meshes. A second-moment turbulence closure employing the transport equations for individual Reynolds stresses is employed in conjunction with wall function approach for near-wall treatment. The numerical results are compared with the experimental data with main focus upon the stem and wake flow. The prediction reproduces, with a remarkable accuracy, all the salient features of the flow such as the cross-flow in the boundary layer and the ensuing stream-wise vortices.
