Comparative steady RANS/MRF CFD study of a D2=560 mm closed centrifugal impeller for Z=11, 16, 17 and 20. Air: rho=1.20 kg/m3, mu=1.8e-5 Pa·s; n=8500 rpm; Q=1.20 m3/s with 0.85Q and 1.15Q cases; SST k-omega; identical mesh strategy and y+; three-mesh independence study. Outputs: head, efficiency, torque, total-pressure loss, separation, velocity distribution and outlet-flow nonuniformity.
