Characteristics of rotating instability in a centrifugal blower with shrouded impeller

Transactions of the JSME (in Japanese), 2014
The Rotating instability, abbreviated to RI, in a centrifugal blower with shrouded impeller is investigated by experiments and CFD analyses. The RI occurs in a partial-flow operation of the blower prior to stall with mild fluctuations of impeller ...
