Numerical simulation of incompressible flows in naval architecture problems

The research activity at IAC-CNR on the numerical simulation of flows around ship hulls will be reviewed. Some simulations of seakeeping, manoeuvring and propulsion problems will be shown in order to highlight the main issues related to the simulation of turbulent free surface flows. The focus of the presentation will be on numerical accuracy and uncertainties, space discretization for complex geometries with moving boundaries, parallel computation and turbulence modelling for unsteady flows.
