... Abstract The paper outlines the CFD study carried out on the Highly Efficient Centrifugal Compressor (HECC) consisting of three blade rows which are an Impeller (main blade/splitter blade), a Diffuser (main/splitter vane) and a Deswirl. The commercial Ansys CFX 2021R2 CFD package has been used...

... Abstract Centrifugal compressors can be subjected to non-uniformity in inlet flows due to complicated inlet pipe geometries arising from space constraints and the wakes of protruding instrumentation, impacting the compressor’s performance. Inlet distortion can cause premature stall initiation...

... Abstract The diffuser vane of the high-speed centrifugal compressor is subjected to lean in the current study’s numerical analyses.Lean can be defined as a shift in the stagger angle in the vane’s span-wise direction. Three different leans, including lean at the vane’s leading edge, trailing...

... Abstract Centrifugal compressor has widespread applications in areas such as aerospace, automotive, power and process industries and hence the prediction of its performance is crucial at the design stage. Traditional design, build and test are accelerated through numerical simulation...

... This paper presents the results of numerical studies on the effect of endwall reshaping on the performance and stall margin of a centrifugal compressor. The endwall (shroud) of a baseline compressor was reshaped by introducing a convex hump at a location downstream of the inducer where the flow...
