Effects of Blade Wrap Angle Influencing a Pump as Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A pump is not ideally designed to operate as a turbine. To improve the efficiency of a pump as turbine (PAT), the redesign of the PAT, according to the flow of the turbine, is required. ...
Influence of Blade Number on the Performance and Pressure Pulsations in a Pump Used as a Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rotor-stator interaction of a rotating impeller and a stationary volute could cause strong pressure pulsations and generate flow induced noise and vibration in a pump used as a turbine ...
Experimental, Numerical, and Theoretical Research on Impeller Diameter Influencing Centrifugal Pump-as-Turbine
Publisher: American Society of Civil Engineers
Abstract: One of the limitations of using the pump-as-turbine (PAT) technique is its relatively narrow high-efficiency operating range. When the system pressure head or flow rate decreases, trimming the impeller or replacing the ...
