DOMAIN DECOMPOSITION IN FREE SURFACE VISCOUS FLOWS
The computation of the steady free surface flow past a ship hull is performed by a domain decomposition approach. Viscous effects are taken into account in the neighbourhood of solid walls and in the wake by solving the Reynolds Averaged Navier-Stokes equations, whereas the assumption of irrotationality in the external flow allows a description by a potential model. Free surface boundary conditions have been implemented in a linearized form at the undisturbed waterplane. Suitable matching conditions are enforced at the interface between the viscous and the potential region. The numerical results obtained for the HSVA tanker and the S60 hull
