For the effects on compressor efficiency, Klassen studied the tip clearance effects using a 13.65-cm-tip-diam centrifugal compressor designed for small-engine applications. Most of these efforts focus on stage efficiency, total pressure ratio, and work input. The effects of tip clearance on compressor performance parameters have been investigated extensively using both experimental and numerical approaches. As the engine tip clearance increases during its service lifespan, the ability to predict the effects of tip clearance and include such effects into the design process becomes crucial. The tip leakage vortex is a significant contributor to secondary flows inside the compressor and adversely affects both the stage and the component performance. Lastly, numerical simulations at design speed showed that the computational fluid dynamics (CFD) model sufficiently predicts the sensitivities due to tip clearance for most of the parameters at the stage and component levels, indicating the potential of using CFD to investigate the flow physics.ДЇ low through the impeller tip clearance in centrifugal compressors can significantly impact the performance of the stage. As the compressor transitions from subsonic to transonic operation from 60 to 85% corrected speed, the sensitivities of stage and impeller pressure ratio and efficiency reach their peak values. With increased clearance, the stage and impeller pressure ratio, isentropic efficiency, and work factor drop, but the static pressure recovery coefficient in the diffuser increases.

Experiments were conducted on the Single Stage Centrifugal Compressor facility at two different running tip clearances. To fill this gap, this paper investigates the effects of impeller tip clearance on the performance of a high-speed centrifugal compressor, at both stage and component levels, covering a variety of operating speeds resulting in subsonic to transonic inlet conditions. However, most of the previous investigations focus on stage-level analysis at the design condition, with very limited studies at the component level or part speed conditions. Extensive research studying tip clearance effects on compressor performance has been conducted during the past few decades with significant progress achieved.
