Detailed experimental measurements of the flow in a cascade of turbine rotor blades with a nonplanar end wall are reported. The cascade geometry was chosen to model as closely as possible that of a H.P. gas turbine rotor blade. The blade section is designed for supersonic flow with an exit Mach number of 1.15 and the experiments covered a range of exit Mach numbers from 0.7–1.2. Significant three-dimensional effects were observed and the origin of these is discussed. The measurements are compared with data for the same blade section in a two-dimensional cascade and also with the predictions of two different fully three-dimensional inviscid flow calculation methods. It is found that both these calculations predict the major three-dimensional effects on the flow correctly.

Data Result

A computation method for the three-dimensional rotational flow through transonic and supersonic rotors is described and discussed by means of a comparison with experimental results. The computation treats subsonic and supersonic flows with different algorithms. The compression shocks are calculated as real three-dimensional discontinuities on the basis of the Rankine-Hugoniot-equations. The experimental data result from measurements in transonic and supersonic compressor rotors. A comparison of the data shows to what extent these three-dimensional effects are covered by the described theory.
