Abstract

This paper presents a comparison of different numerical software packages for the flow simulation of a centrifugal compressor at the example of the RADIVER testcase. Three dimen-
sional steady state numerical simulations have been carried out with the Numeca and OpenFOAM CFD codes. The used turbulence models are Spalart-Allmaras and k-ω SST, which were also coupled with a conjugate heat transfer (CHT) simulation.
All simulations are analyzed in the compressor map along with the experiments. The temperature distributions of the CHT simulations are examined and their implications reviewed. The simulations cover three operating points at 80% design speed. One operating point of the fluid simulations near the surge line is compared in detail to the data from experiments conducted on the compressor. Velocity vector components and turbulence intensities are plotted and reviewed. Similarities and differences are discussed and their causes and effects pointed out.
