Full Scale and Model Scale Propeller Ventilation Behind Ship

In the present paper the results from several experimental campaigns aimed to better understand the phenomenon of propeller ventilation are presented. The paper includes both reanalysis of already published data and the analysis of new experimental data. The presented data were collected both in full scale and in model scale. The model scale data features propeller open water tests in the towing tank and free running model in calm water and in waves in the ocean basin. Both set of experiments were carried out in MARINTEK facilities. The full scale data were recorded by means of a ship propulsion monitoring system called HeMoS, developed by Rolls Royce Marine. The full scale data have been used as a basis for the tests in the ocean basin. This work was carried out in the framework of Era-Net Martec project PropSeas.
