Vector Velocity Fluctuations of Propagating Stall in Axial Flow Compressors


Bodeen, Charles Albert (1961) Vector Velocity Fluctuations of Propagating Stall in Axial Flow Compressors. Engineer's thesis, California Institute of Technology. doi:10.7907/X72A-P111.


The angular velocity of propagation of a single cell partial span propagating stall traveling on an isolated, or relatively isolated, axial compressor blade row was found experimentally to be equal to the downstream angular velocity of the flow outside the stall cell between successive passages of the stall cell averaged over the blade span. In a machine consisting of three identical stages, a similar stall was found to propagate at the mean of two such averages, i.e., upstream and downstream from any interior blade row. The sides of partial span stall cells were found to be streamtubes in several cases. Other general but less significant observations of propagating stall are reported. The hot wire anemometers used to measure unsteady vector velocities are described.
