Book Description

The performance of a 12.62-cm (4.97-in. ) tip diameter radial-inflow turbine was investigated over a range of specific speeds from 0.28 to 0.73 (39 to 94) at equivalent design speed and pressure ratio. The specific speed range was obtained by using stators with different throat areas. The stators were used with the design rotor, with a rotor exducer extension that reduced the rotor throat area, and with the rotor exducer cut back to increase the rotor throat area. The efficiencies obtained with the three rotor configurations are presented and compared.
