Rotating stall in the radial vaneless diffuser with large radius is studied experimentally. The static pressure on the wall and the velocity distribution are measured and analyzed, and the critical flow angle calculated theoretically is compared with the experimental one. Measured velocity distributions show that the existence of reverse flow is closely related to the occurrence of stall. In our study, rotating stall occurs at a much larger flow angle than that in conventional studies. Also, in a wide range of flow angle, a compound pressure vibration of two different frequencies is observed, which shows the steady coexistence of two different types of stall cells. Furthermore, the dimensionless frequency of stall propagations is more stron...
