An aerodynamic performance analysis is essential for nearly all aspects of radial-inflow turbine aerodynamic design and application. The highly complex three-dimensional flow fields in these machines are strongly influenced by viscous effects and passage curvature. In contrast to the axial-flow turbine, the most effective approach to the performance analysis of radial-inflow turbine is the one-dimensional or mean-line method. Indeed, there is a close parallel with compressor performance analysis where the one-dimensional method is the most effective technique for the centrifugal compressor [1] but the more general hub-to-shroud flow method is the better choice for the axial-flow compressor [2].
