Based on the analysis of physical and geometric features of turbine characteristics, a flow and efficiency-characteristics fitting model for variable-nozzle turbines is provided. A new "two step" method for determining the unknown parameters of the mathematical fitting model is suggested. With this model, the characteristics of a variable-nozzle power turbine have been fitted. As compared with the original data, the average relative errors of the corrected flow and efficiency obtained from the model are 0.675% and 0.534% respectively. In addition, the flow characteristics of a high-pressupe turbine with 2 independent variables have also been fitted, the avenge relative error being 0.638%. Thus, the results obtained from the present model may be considered satisfactory.
