... facility has two controls: the motor and the eddy-current brake. The variable speed motor drives the centrifugal fan, at the rear of the facility, which draws ambient air through the working section. This effectively sets the mass flowrate through the facility. The eddy-current brake absorbs the power...

... coefficients are achievable explicitly through the modification of the axial velocity (fan throttling). Given that the effect of the flow coefficient is negligible to the rotor exit flow profiles (see Figs. 12 and 13 ), reducing the flow coefficient has a similar effect to increasing the bleed. In this way...

To demonstrate this, two example design cases are shown in the paper: a transonic rotor within a multistage civil compressor with variable upstream stator vanes, and an embedded rotor within a multistage military fan. The method is shown to (1) improve both...

... to the integration of three-dimensional design into the rotor and stator blade. Goswami and Govardhan [ 21 ] noted that a positive increase in lean increases the stall margin up to some optimal value and then decreases. In another experimental study on multistage fans, Wadia [ 22 ] reported a higher stage efficiency...
