(2008), “Free Surface Flow Around Ship Hulls Using an Interface-Capturing Method”, Proceedings of the 27th International Conference on Offshore Mechanics and Arctic Engineering (OMAE´08), 15-20 June, 2008, Estoril, Portugal, ASME, New York, Paper OMAE2008- 57987
In the present paper, a compressible free surface code is used for simulating the flow around ship hulls. The code simulates both turbulent and laminar, free-surface flow around ship hulls, using the Slightly Compressible Flow formulation. The runs were performed for a Series60, Cb=0.6 hull in standard conditions of Froude numbers and the results were compared against experimental and numerical results. The turbulence model used is Baldwin-Lomax. The numerical scheme was marched in time using the 2nd order, explicit Runge-Kutta. For the time being, the code uses a fixed grid on which the kinematic free surface equation is solved. Several boundary conditions were implemented and their behaviour assessed. The results show fair agreement with the experimental results.
