The Developed Cavitation Dynamics and Intensity and Examination of Inception in Vortical Wakes
Abstract
Approved for Public Release. This work investigates the effects of mixture compressibility on the shedding dynamics and cavitationcollapse intensity in cavitating flows. X-ray densitometry and X-ray Computed Tomography (X-ray CT) is used to make quantitative void fraction measurements in developed cavitatating flows observed in canonical geometries. In addition, synchronized surface pressure measurements are also performed. To study 3-D flows a blow-down test facility, capable of operating at a range of cavitation numbers and flow speeds is built and tested. In addition to high void fraction X-ray based measurements, this study also examines cavitation inception observed on vortical wakes.
