Experimental Investigation of the Stalled Flow of a Single-Stage Axial Flow Compressor
Published online by Cambridge University Press: 07 June 2016
Summary
Experimentally it is shown that variation of axial spacing between neighbouring blade rows can alter the stall characteristics of a compressor stage. The stall cell patterns of this compressor stage are described in detail and changes of slope in stage temperature and pressure rise characteristics are explained in terms of stall propagation. Strain gauge tests on stator blades are used to indicate the possibility of large dynamic stresses occurring when the stall cell frequency is equal to the blade natural bending frequency.
