Pressions instationnaires générées par une poche de cavitation partielle
Pressure fluctuations downstream a leading edge cavity
Institut de machines hydrauliques et de mécanique des fluides Ecole Polytechnique Fédérale de Lausanne 33, avenue de Cour, CH 1007 Lausanne
To validate the erosive power model that we have formerly introduced, we intend in this work to compare the erosion tests previously performed on a NACA009 blade with wall pressure fluctuations measured downstream a leading edge cavity. Furthermore. the video acquisition of the main cavity length helps us in finding out the relationship between the vortex shedding frequency and the main cavity pulsation.
