Design of the Basic Performance Characteristics Maps of an Axial Flow Turbine Stage

Performance charts for the preliminary design of an axial turbine stage have been constructed from the three basic dimensionless performance parameters reaction ratio (R), flow coefficient (?), and stage loading coefficient (?). The charts are completed with constant nozzle outlet flow angle lines, estimated efficiency contours. The performance charts may be used to evaluate; the optimum values of performance, dimensionless parameters, flow coefficient, flow angles, stage efficiency for any reaction ratio.
