The aim of this test case is to obtain insight into the capability of CFD to predict model-scale cavitation dynamics, pressure pulses and underwater radiated sound. The Polish research ship Nawigator XXI has been selected by the International Towing Tank Committee (ITTC) for benchmarking underwater radiated noise measurements of cavitating propellers. Although the ship is relatively small, it is a single-screw vessel with a hull representative of a commercial vessel. Currently, experimental results are not (yet) available, so the workshop will concentrate at comparisons between CFD results. The metrics to be investigated are the propeller revolution rate, time- and frequency-domain pressure signals, and flow-visualisation data.
