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 “running” blade profiles as designed and one using the

Two transonic mixed flow compressors with an extremely high flow coefficient of ϕ = 0.25 and pressure ratios of 2.5 and 2.65 have been designed and tested. CFD simulations indicated that both impellers operate with a suction surface relative Mach nu
The design of a mixed flow compressor stage with an extremely high flow coefficient ( ϕ ) of 0.25 and a high pressure rise coefficient ( ψ ) of 0.56 is described. The objective of the work was to explore the performance potential in this highly unc

The aim of the current paper is to investigate the evolution of the flow in the vaneless diffuser of a scaled-up turbocharger compressor using the steady-state viscous calculations. First, the predicted flow patterns are compared with the detailed la

The objective of the current paper is to employ numerical simulations to identify flow features, which could lead to the breakdown of stable operation in transonic centrifugal impellers at near-stall operating conditions. Steady state three-dimension
