Definition
Cavitation is the process of nucleation in a liquid and subsequent formation of gas/vapor phase when the pressure falls below a critical value. Researchers studying cavitation address topics ranging from the initial appearance of cavities in liquids (cavitation inception) to the development of large-scale cavities (supercavitation).
Overview
Cavitation, the phenomenon that causes liquids to rupture and to form vaporous/gas cavities when subjected to sufficiently low pressures, can occur in any machine handling liquid when requisite hydrodynamic conditions develop (Fig. 1). Cavitation, in many cases, is an undesirable phenomenon in hydraulic machinery that can limit performance, lower efficiency, introduce sever structural vibration, generate acoustic noise, choke flow and cause catastrophic damage [1]. The pernicious effects of hydrodynamic cavitation on conventional fluid machinery have been recognized and actively...
