Abstract

Detailed measurements through all hot-wire anomometry at the out let of a centrifugal impeller revealed a rotating stall at a flow coefficient of 0.057. As the flow coefficient is reduced to 0.034 the behavior of the rotating stall pattern changes. An experimental method is described to estimate the stall propagating speed and the number of stall cells. These two parameters charecterise the rotating stall in a centrifugal impeller
