Cavitation PhenomenonWhen the pressure drops below the air separation pressure, air dissolved in the liquid is released in the form of bubbles. These bubbles occupy space within the oil, causing the liquid to become discontinuous. This phenomenon is referred to as cavitation. Cavitation and Erosion ProcessAfter cavitation occurs, the bubbles flow into the high-pressure zone, […]
