Abstract

The 3D, steady, viscous flow field in a high speed centrifugal compressor impeller is numerically analyzed by using of Fine/Turbo CFD package from NUMECA. The second order centered scheme and Spalart-Allmaras one equation turbulence model are used. The computed results are validated in details by comparing with the available experimental data, including overall performance, shroud static pressure and relative Mach number at several sections. Effects of grid density and tip gap size, and different approaches for processing the CFD data are discussed.
