Effect of Partial Span Aspiration on the Performance of a Transonic Axial Compressor Rotor: A Numerical Study

Figure 10

Relative Mach number distribution in the blade passage of baseline rotor at three spanwise locations from hub (100% design rotational speed, near-design mass flow rate).

(a) 95% span from hub

(b) 72.5% span from hub

(c) 50% span from hub
