Recherches récentes sur la cavitation à l'Institut de mécanique de Grenoble
Recent researches relating to cavitation carried out at the Grenoble Institute of Mechanics
Two themes combining two various test means are covered: The developed cavitation studied in the IMG's hydrodynamic tunnel and the cavitation erosion studied on a mercury loop. The developed cavitation study includes: the analysis relating to the separation of a cavity from a wall, the unsteady cavitation per pocket, the interaction between germs, the boundary layer and the cavity (this study is dealt wilh in a separate report), and the experimental study of partial cavitation. Erosion tests were carried out in collaboration with the CERG and EDF with a view to clarifying the rules of similarity. Finally, a special effort has been made so as to develop and calibrate miniaturized pressure sensors specially adapted to measure instantaneous excess pressures due to structural implosion.
