Abstract:
A method for calculation of the performance of conventional axial-flow turbines is presented. It makes use of data derived from the analysis of a large number of turbine tests and other associated test work reported elsewhere. The method enables the performance of a turbine to be calculated over a wide part of its full operating range. It is estimated that the tolerance on the absolute values of gas mass flow and peak efficiency will be in the region of ±2.0 per cent for efficiency and ±3 per cent for gas mass flow on present day types of turbine. The method is illustrated by a worked example.
