摘要：
In a turbomachine having an impeller rotating in a casing, nozzles are provided for forming an annular layer of fluid flowing along the inner surface of the casing. The annular flow layer is formed continuously or intermittently under control by detecting the occurrence of unstable characteristics of the turbomachine or a precursor of unstable characteristics, created by conditions represented by a positively-sloped region of the head-capacity curve of the turbomachine.
