Ahmed, Y. e Guedes Soares, C. (2009), “Simulation of the Flow around the Surface Combatant DTMB Model 5415 at Different Speeds”, Proceedings of the 13th Congress of International Maritime Association of the Mediterranean (IMAM 2009), 12-15 October, Istanbul, Turkey, pp. 307-314

The incompressible turbulent viscous flow around the hull form of the DTMB model 5415 at two Froude numbers has been simulated using a commercial RANSE code. The free surface flow pattern around the hull at the two speeds has also been investigated using a potential flow code based on the Rankine source method. The free surface has been treated as a plane of symmetry in the commercial code simulations. The simulations conditions are the ones for which experimental and numerical results exist. The standard turbulence model has been used in the commercial code. The grid generator of the commercial code has been used for generating the unstructured tetrahedral computational grid required for the RANSE code solver, while the quadrilateral structural patches were used with the potential flow code for meshing the DTMB model hull surface and the water surface around it. The results compare very well with the available experimental data.
