This paper presents a selection of CFD investigations on ship and propeller hydrodynamics performed in the frame of an extensive benchmarking activity, presently undertaken in the frame of the OpenSHIP Project - Highly reliable CFD simulations for the prediction of the hydrodynamic performance of the hull-propeller system with OpenSource software - co-financed by the ERDF - European Regional Development Fund - Friuli Venezia Giulia Region Operational Programme 2007 - 2013. Spilling breaking and non-breaking waves induced by a foil at constant speeds underneath the free surface are presented first. The wake at the propeller disk of a double model hull – MOERI KCS - is then analyzed, and finally the numerical predictions of the propulsive characteristics of two different model scale propellers are presented. All the simulations are carried out using the OpenFOAM-2.1.0 CFD package, and the numerical results are compared with available experimental data.

Abstract
This paper presents a selection of CFD investigations on ship and propeller hydrodynamics performed in the frame of an extensive benchmarking activity, presently undertaken in the frame of the OpenSHIP Project - Highly reliable CFD simulations for the prediction of the hydrodynamic performance of the hull-propeller system with OpenSource software - co-financed by the ERDF - European Regional Development Fund - Friuli Venezia Giulia Region Operational Programme 2007 - 2013. Spilling breaking and non-breaking waves induced by a foil at constant speeds underneath the free surface are presented first. The wake at the propeller disk of a double model hull – MOERI KCS - is then analyzed, and finally the numerical predictions of the propulsive characteristics of two different model scale propellers are presented. All the simulations are carried out using the OpenFOAM-2.1.0 CFD package, and the numerical results are compared with available experimental data.Pubblicazioni consigliate
