An Investigation on the Loss Generation Mechanisms Inside Different Centrifugal Compressor Volutes for Turbochargers

Abstract: In centrifugal compressor design, the volute plays a key role in defining the overall efficiency and operating range of the stage. The flow at the impeller outlet is indeed characterized by a high kinetic energy content, which is first converted to potential energy in the diffuser downstream. The compressed gas is then collected by the volute at the cylindrical outlet section of the diffuser and directed to the intake piping, possibly with a further pressure recovery to enhance the stage performance. Due to th… Show more

“…As an asymmetric geometry component, the volute leads to the formation of a circumferentially non-uniform flow field in the compressor and seriously affects the performance and stability of the compressor. [6][7][8] Recently, increasing researchers have focused on the influence of the downstream static pressure distortion induced by the volute on the centrifugal compressor stall. In fact, the volute is a type of gas collecting and guiding device.…”
