Acoustic Analysis of Vortex-based Cavitation Devices: Inception and extent of cavitation
Industrial & Engineering Chemistry Research, 2021 Hydrodynamic cavitation (HC) is a process of generation, growth and collapse of gas/vapour filled cavities leading to intense shear and localised hot spots. It is essential to identify the inception and extent of cavitation for ensuring appropriate operation of HC devices and processes.
