In the frame of a joint research programme between EDF, Hydro-Québec and IMHEF, different methods are investigated to predict cavitation erosion on Francis turbines from model. They are based on measurement of pitting, pressure fluctuations and acceleration. The measurement techniques have been detailed in Part 1 and Part 2. The present article describes essentially the theoretical and practical aspects of the methods and discusses the results obtained until now from the model and prototype tests. The first analysis shows that the methods proposed are suitable to measure cavitation aggressiveness on model and on prototype, and that the level on the model is several orders of magnitude smaller than on the prototype. To adjust transposition laws, a more complete set of data is needed.
