DOI: 10.1063/5.0299174
Abstract: The polishing quality of cavitation–abrasive synergistic processes critically depend on the flow characteristics and its wall-loading mechanisms. In this study, a bidirectional volume alternating cavitation (BVAC) method for generating global cavitation in microchannels was proposed.… read more here.
