..., the flow instability mechanism of the highly loaded compressor at different corrected speeds was clarified through the experiments. At 50% corrected speed, the compressor rotor developed from a spike-wave stall precursor to a rotating stall; at 70% corrected speed, the compressor developed directly from...

... machines. This frequency is often used as a base frequency for the description of aerodynamic processes. The flow instabilities occurring in compressors usually consist of a rotating pressure field called a rotating stall. The instability can be characterized by the frequency of rotation...

... streamlines, shows that the blade tip water injection could help in reducing low energy region downstream of the shockwave and strength of the tip leakage vortex with the compressor operating at its rotating stall boundary condition. The extent of reduction depends on the droplet size, injection flow rate...
