Abstract : This investigation was aimed at developing more sophisticated shock models to be incorporated in an off-design performance prediction method for transonic axial flow compressor stages for more accurate flow prediction. Primary emphasis was given to the improvement of shock models used for evaluating the shock losses, especially, at supercritical subsonic, but also at supersonic inflow conditions. The newly developed and refined methods were verified by calculating, investigating and analysing the losses of compressor cascades, as well as of a transonic axial flow compressor.
