PRESSURE FLUCTUATIONS AROUND A MARINE PROPELLER. RESULTS OF CALCULATIONS AND COMPARISON WITH EXPERIMENT

In the report some methods for the calculation of the pressure field around a propeller in the free stream case are briefly outlined and applied to some cases for which experimental information is available. Further the extension to the case of a propeller in a wake is made and results of comparisons between calculations of this kind and experimental results obtained with propellers in behind condition are presented and discussed. Finally the influence of some parameters on the pressure fluctuations in different points around a propeller is calculated for propellers in open water condition and in different wake distributions. Some conclusions drawn from the results are summarized. (Author)
