A Parametric Investigation of Geometric Variation on Fluid Dynamic Instabilities in Axial Compression Systems

Figure 11

Effect of increase in mean annulus area of compressor: variation of nondimensional flow properties (a), (b), and (c) with time. (a) Axial flow coefficient, (b) plenum pressure rise coefficient, and (c) disturbance amplitude of rotating stall. (d) Variation of axial flow coefficient with disturbance amplitude of rotating stall. (e) Variation of plenum pressure rise coefficient with disturbance amplitude of rotating stall. (f) Limit cycle oscillation: axial flow coefficient versus plenum pressure rise coefficient.
