RISSuppression of Rotating Stall by Wall Roughness Control in Vaneless Diffusers of Centrifugal Blowers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By positioning the completely rough wall locally on the hub side diffuser wall alone in the vaneless diffuser, the flow rate of rotating stall inception was decreased by 42 percent at a small ...
Suppression of Unstable Flow at Small Flow Rates in a Centrifugal Blower by Controlling Tip Leakage Flow and Reverse Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of the inlet recirculation arrangement on inducer stall and the diffuser width on diffuser stall in a high-specific-speed-type centrifugal impeller with inducer were analyzed by ...
