The incompressible free surface flow around a Wigley hull form has been simulated using a commercial RANSE code using the two-phase Eulerian-Eulerian fluid approach, and a potential flow code using on the Rankine source method. The flow has been simulated around the hull at two Froude numbers and comparisons between the results and the experimental results have been made. Two turbulence models (k-ƒÃ and Shear Stress Transport) are used in the commercial RANSE code. The computational grid in the commercial code has been used for generating the unstructured tetrahedral and structured hexahedral computational grid required for the RANSE code solver. The potential flow code uses quadrilateral structured patches to mesh both the ship hull surface and the water surface around the hull. In all the simulations, the hull is fixed. The results compare well with the available experimental data.
