The aerodynamic performance of high-specific-speed mixed flow compressors was studied. The specific speed, N_s, was 450 to 550 (m^3/min)^<1/2> (rpm) (m^<-3/4>), with approximately a 2.0 pressure ratio per stage. The meridional flow path from the outlet of the mixed flow impeller was inclined in the axial direction and entered into a curved diffuser. A theoretical flow analysis and performance test were carried out. Distributions of the flow velocity, temperature probe. The flow, including the boundary layer, was surveyed. The mixed flow impellers showed high efficiency and handled a flow rate of about three times as much as that of conventional centrifugal impellers. This development contributes tremendously to reducing the compressor size. A 200000m^3/h multi stage compressor of this design is in operation.
