Abstract
After an introduction to the aerodynamic problems facing the designer of large steam turbines, two analytical methods that have been used to analyse the flow in such turbines are reviewed, and their limitations discussed. Results are given for an analysis of a single-stage machine similar to that found in an intermediate pressure steam turbine using the matrix through-flow programme to investigate the effects of varying blade twist, tilt, blade thickness, and camberline shape. In addition, details are given of a comparison made between results obtained from a streamline curvature and a matrix through-flow programme used to analyse a single-stage turbine. Finally, the problems of using these programmes are discussed, and details of the effect of grid shape and damping factor are given.
