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