As advocated by Denton [1], three-dimensional CFD calculations are more and more used in the process of designing centrifugal compressors. Therefore, numerical accuracy is an issue if valuable design decisions are to be based on CFD results. This paper aims at correlating mesh-parameters and calculated flow quantities. The design-of-experiment method (DOE) is used to identify which mesh-parameters influence any given flow quantity. The emphasis is put on global performances (mass-flow rate, pressure-ratio and efficiency), and on local features (friction co-efficients and local velocity-profiles). The outcome of the study is the connection between mesh-parameters and specific flow-properties. This can be further used to derive numerical bench-marks, such as reported by Dufour et al. [2] for the tip-clearance flow.
