This paper presents the numerical analysis and aerodynamic optimisation of a return
channel system and U-turn for multi stage single shaft centrifugal compressor machinery. An …

Steady-state simulations of a high-flow centrifugal compressor stage with return channel for
industrial applications are carried out to determine the flow conditions in a new compressor …

In this study, aerodynamic design improvement options are explored for a low vane count
and high flow-coefficient stage return channel, which was found to produce larger than …

In this paper, steady RANS (Reynolds-Averaged Navier-Stokes) numerical modeling of the
return system of a centrifugal compressor is carried out to investigate the effects of various …

For multi-stage compression systems, besides the aerodynamics of the impeller and the
diffuser, the U-turn and return channel blades aerodynamics play an important role for the …

Optimal gas-dynamic design is a complex and time-consuming process. Modern CFD
methods help in solving optimization problems and reliably calculating characteristics of …

A full-annulus cascade for radial compressor stator development has been designed and
commissioned. The cascade has been developed for the rapid screening of novel stator …

This paper describes the optimal design and experimental verification of centrifugal
compressors with leaned curvilinear element blades. The design targets were a fully …

The present paper deals with the numerical and experimental investigation of the effect of
return channel (RCH) dimensions of a centrifugal compressor stage on the aerodynamic …

The effects of a return channel with splitter vanes on the performance of a multistage
