Abstract: The aim of the current paper is to investigate the evolution of the flow in the vaneless diffuser of a scaledup turbocharger compressor using the steadystate viscous calculations. First, the predicted flow patterns are ...

Abstract: The impact of the hub and shroud leakage flows on the compressor efficiency has been investigated for four compressor stages with flow coefficients of 0.017, 0.0265, 0.063, and 0.118 belonging to a family of centrifugal ...

Abstract: This paper describes the design of a transonic mixed flow compressor stage for an extreme duty, with an extremely high flow coefficient (د†) of 0.25 and a high isentropic pressure rise coefficient (دˆ) of 0.56. The impeller ...

Abstract: The effects of blade deformation under running conditions on the performance of a highly loaded transonic mixed flow impeller were investigated. Two impellers were manufactured, one using the “runningâ€‌ blade profiles ...

Abstract: The detailed design of the inducer of a high pressure ratio transonic radial compressor impeller with a design inlet tip relative Mach number of 1.4 is considered. Numerical analysis has been used to compare a datum impeller ...
