Développements récents d'une méthode de prévision de l'érosion de cavitation
Recent developments concerning a method for forecasting cavitation erosion
Alsthom CERG, Le Pont de Claix
2 Bassin des Carènes, Le Val de Reuil
In the first part, the authors refer to the laws of similarity of a quantitative forecast method concerning erosion produced by a cavitation flow and give the results of validation tests carried out in various laboratories (Alsthom-CERG, EDF and the Grenoble Institute of Mechanics). The second part relates to the analysis on the basis of the test results of the effect of dissolved air on erosion produced by a pocket cavitation. The third part gives an account of the steps taken concerning the continuation of the development and the use of the method, determination of impact histograms by optical measurement and the development of a controlled simulation measuring device of cavitation erosion impacts.
