EXPERIMENTAL STUDIES TO ESTABLISH SCALING LAWS FOR MODELING CAVITATION DAMAGE INTENSITY

An experimental facility called the rotating foil apparatus was designed and built to study cavitation erosion in an actual but controllable hydroynamic system. Test results from this apparatus have confirmed the time dependence of cavitation intensity and also indicated the relationship between erosion intensity ( I SUB E ) and cavitation parameter ( Sigma ) for an NACA 16-021 foil section at 181 ft/sec. A family of the I SUB E versus Sigma curves is sought for several velocities so that the true relation between I SUB E and velocity can be established thus providing a clue of the pressure which causes the bubbles to collapse. Additional testing is planned to determine the relationship between Reynolds number ( RE ) and erosion intensity ( I SUB E ) for several values of cavitation parameter ( Sigma ). The ultimate objective is modeling cavitation erosion. ( Author )
