초록

A turbomachine having an impeller rotating within a casing of the machine and groove passages are formed in a wall of the casing between an upstream portion and a downstream portion of the impeller and high pressure fluid is injected into the groove passages for increasing the stall margin without lowering the peak efficiency of the machine and prevents generation of a positive slope in a head-capacity curve.
