Abstract
asurement of rotating stall in the largescale,
low-speed axial compressor facility.
The purpose of the study was to make initial
attempt to characterize the overall
phenomenon of rotating stall by measurement
of hot-wire signature upstream of the rotor
row. Measurement was taken at stall-onset
flow coefficient with rotor/stator blade
configuration. Data show clear characteristic
of time-mean steady flow entering into
rotating stall flow. The precursor region
shows a clear growth of the instability and
finally developing into a full-scale rotating
stall phenomenon. The frequency of the stall
cell is shown to be 0.93 that of the shaft
frequency, which means that one stall cell per
rev characterize this axial compressor.
Moreover the signature of the hot-wire
suggests that the spatial extent of the stall cell
is fairly small.
