Book Description
The flow to the rotor of a single stage axial transonic compressor was found to be in disagreement with design requirements. The incidence angle to the rotor blading was measured to be towards stall in the hub and tip regions when close to design near center-span. Hardware modifications were made, guided by flow field calculations. Predictions were compared with measurements. The most significant improvement was obtained by increasing the flow rate at open throttle. No practical method to correct the flow near the hub was found.
