Vortex Fluid Flow for Generation of Hydrodynamic Cavitation Aimed at Enhancing Manufacturing Processes
Department of Mechanical and Aerospace Engineering North Carolina State University Raleigh NC 26795 USA
ABSTRACT
The energy emanating from hydrodynamic cavitation can play a significant role in enhancing manufacturing processes that utilize fluid medium as a force transmitter, a lubricant, or as a carrier. The fluid flow characteristics in a vortex cavitation generator is studied to determine how bubbles could be transported to a target location prior to implosion. Preliminary CFD simulations and experimental results have shown that the cavitating fluid stream exhibits a swirl flow pattern causing the cavitating stream to remain at the core of the stream. This phenomenon opens avenues for developing mechanisms for controlling and transporting cavitating bubbles to target locations prior to implosion.
Keywords: Hydrodynamic Cavitation, CFD, Water Cavitation Peening, Cavitation Polishing.
