An Application of Bubble Collapse Pulse Height Spectra to Venturi Cavitation Erosion of 1100-o Aluminum

Venturi cavitation erosion tests were performed and correlated with bubble collapse pulse height spectra measured by a microtransducer. The effects of the throat velocity and the cavitation number u (referred to the downstream pressure and throat velocity) on the erosion rate (MDPR) were studied. The velocity damage exponent was 4.11 for 0.62 < u < 0.80… (More)
