CORRELATION RESULTS OF MODEL AND FULL SCALE DUCTED PROPELLER CAVITATION OBSERVATIONS

In adopting the ducted propeller for a 280,000 DWT tanker, the M.S. 'THORSAGE', the authors conducted model tests in the cavitation tunnel and in the NSMB depressurized towing tank (vacuum tank) to study the ducted propeller cavitation. Also full scale cavitation observations were carried out successfully during the sea trials of the M.S. 'THORSAGA' using a T.V. camera scanning the propeller. The observed results were recorded on video tape. Results of the cavitation tunnel and vacuum tank experiments are presented together with the full scale cavitation observations, and the correlation between the model and full scale observations is discussed. The model test procedures are also described.
