Implication

Experimental investigation shows improved performance of a transonic centrifugal compressor with a vaned diffuser, indicating its suitability for rotorcraft applications.

Key Points

Choking effects were identified, with impeller stall observed up to 95% of normal operation, indicating operational limits.
The slip factor was determined to be 0.96±0.03, effectively predicting performance across rotational speeds.
A range of turbulence models were validated against empirical data, supporting the reliability of the numerical method employed.
Diffuser throat size may limit performance, suggesting potential modifications for optimal compressor operation.
