The domestic and international research status of rotating stall in turbomachinery was presented.First

the relevant conclusions on the theoretical model

experiments and numerical simulation of rotating stall were introduced

and the current research methods were analyzed in detail.Then

the hot issues about the stall inception and active control

such as the different forms and mechanisms of stall inception

the connection between leakage vortex and stall

were summerized.Finally

according to the existing problems

the future direction of the studies on the mechanism and active control of rotating stall were discussed

namely the mechanism and influence factors of stall inception

the energy loss mechanism and fluid-solid coupling under stall conditions

and the engineering application of active control technology.
