4. Tabulated ResultsThe first table below gives a summary of the performance results for the centrifugal compressor rotor. Thesecond table lists the mass or area averaged solution variables and derived quantities computed at theinlet, leading edge (LE Cut), trailing edge (TE Cut) and outlet locations. The flow angles Alpha and Beta arerelative to the meridional plane; a positive angle implies that the tangential velocity is the same direction



as the machine rotation.
