The primary scientific goal of the project ProNoVi was to make progress beyond state-of-the-art in theoretical understanding and practical simulation of complex, multi-disciplinary problem of ship and propeller hydroacoustics. To this end, the project employed advanced experimental techniques, both in model scale and full scale, to predict propeller noise and to collect accurate data for the validation of numerical methods, high-fidelity CFD solutions and practical engineering tools that can be used at early design phases. The developed tools were applied to selected target cases of ships and propulsion systems with the focus on noise reduction measures. The project ProNoVi demonstrated that the Scale Resolving CFD method provide a good basis for the numerical prediction of pressure fluctuations and noise induced by propellers, when coupled with a meshless approach of acoustic analogy. Validated against experimental data, the numerical tools developed in ProNoVi were employed by the industrial partners for the development of noise reduction measures on individual target ship cases, without significantly compromising ship's energy efficiency.
