Scaling of cavitation erosion progression with cavitation intensity and cavitation source [PDF]

open access: yesWear, 2012
Abstract A simple mathematical expression is presented to describe cavitation mean depth of erosion versus time for cavitating jets and ultrasonic cavitation. Following normalization with a characteristic time, t* , which occurs at 75% of the time of maximum rate of erosion, and a corresponding material characteristic mean erosion depth, h* , the ...
