EFFECT OF FORCED ROTATING VANELESS DIFFUSERS ON CENTRIFUGAL COMPRESSOR STAGE PERFORMANCE [PDF]
Journal of Engineering Science and Technology, 2011 Non-uniform flow at the exit of the centrifugal impeller mixes in the vaneless space of the diffuser causing a rise in static pressure as well as significant loss of total pressure.

Phase‐Averaged Method Applied to Periodic Flow Between Shrouded Corotating Disks [PDF]
International Journal of Rotating Machinery, 2002 This study investigates the coherent flow fields between corotating disks in a cylindrical enclosure. By using two laser velocimeters and a phase‐averaged technique, the vortical structures of the flow could be reconstructed and their dynamic behavior was observed.

Impeller Design of a Centrifugal Fan with Blade Optimization
International Journal of Rotating Machinery, 2011 A method is presented for redesigning a centrifugal impeller and its inlet duct. The double-discharge volute casing is a structural constraint and is maintained for its shape. The redesign effort was geared towards meeting the design volute exit pressure
