The Centrifugal Compressor Inducer [PDF]
Volume 1: Turbomachinery, 1998 The function of the centrifugal compressor inducer is to provide wide flow margins from the design flow to the stall and choke flow limits, together with high static pressure recovery. At transonic conditions the inducer becomes the critical to impeller performance in that shock losses and blockage growth diminish stable flow range and may trigger near

Development and Design of a Centrifugal Compressor Volute [PDF]
International Journal of Rotating Machinery, 2005 The volute is one of the key components of a centrifugal compressor. The design of the volute not only impacts the compressor efficiency but also influences the operating range. The detailed flow simulation presented here helps to better understand the volute flow mechanisms and provide design guidance in volute design to meet performance goals.
