Verification of Cavitation Damage Prevention of Mixed Flow Pump Impeller by Trailing Edge Shape Modification

Among mixed flow pumps used in various applications, movable-blade type mixed flow pumps have advantages, that is, maximizing the pump efficiency and the suction performance by adjusting the blade angle appropriate to the operating discharge flow rate. However, we have experienced the severe cavitat...
