This report presents an analytical and experimental data base intended as support in the development of new and the refinement of existing codes for computing internal Sows in aero engine components, specifically in cascades, compressors, turbines and ducts ahead of and between them. All the analytical test cases described in this report are relevant to steady, 2-dimensional, inviscid flow calculations. The experimental test cases are relevant to steady 2-dimensional, quasi- or fully 3-dimensional flow calculations for viscous flows in axial turbomachinery components. These data arc believed to represent the highest quality analytical and experimental test cases available today. However, the WG necessarily had to consider what the requirements for a satisfactory test case are and what experimental precautions and problems have to be addressed and overcome. It also became apparent where gaps exist in the available test cases and what is required for the future.
