Suppression of Performance Curve Instability of an Axial-Flow Pump by Using a Double-Inlet-Nozzle

It has been shown that the sudden decrease of pump head in an axial flow pump caused by stall can be overcome by means of casing treatment. Flat axial grooves in front of the impeller break the swirl of the near-casing backflow. The disadvantage of this method is strong cavitation at the inlet of th...
