The results of an analytical study on a centrifugal stage using a commercially available steady state 3D CFD algorithm is presented in the paper. The principal finding from this study is that for a typical product application, the steady state stage simulation is in good agreement with the available test data. In particular, the diffuser characteristics of loss and recovery predicted by the stage CFD analysis agree very well with the test data. The results indicate that for centrifugal compressors in this class, steady state stage CFD may be an effective design tool.
