摘要

Flow visualization and measurements of hydrodynamic cavitation were carried out in a rectangular (22 mm long, 1.5 wide and, 225 μm high) for a 150 μm diameter micro pillar inside. Distilled water was used as working fluid and pressure difference between inlet and outlet tanks utilized as the driving force to produce cavitation. High-speed camera captured cavitation starting from inception to an elongated one. Stochastic nature of phenomenon resulted in significant delays in witnessing cavitation for all experimental runs which may be attributed the dominance of surface tension force at this scale. Almost constant incipient cavitation numbers were achieved and no tangible dependency between cavitation inception number and pressure difference across the channel was observed which agrees well with previous studies.
