Abstract
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.
