Abstract

Surge and rotating stall often damage a compression system. Ishii et al showed the possibility of these unsteady phenomena occurring simultaneously in an axial compressor. In this paper, we examined relation between surge and rotating stall in a small centrifugal compressor. Our experimental results showed that both surge and rotating stall occurred simultaneously in the test centrifugal compressor.
