Study on cavitation influence for pump head in an axial flow pump

Journal of Physics: Conference Series, 2015
The size of axial flow pumps used in drainage pump stations has recently decreased, and their rotation speeds have increased, causing an increase in the risk of cavitation. Therefore, to provide highly reliable pumps, it is important to understand the internal flow of pumps under cavitating conditions.
