Two-Dimensional Inflow Conditions for a Supersonic Compressor With Curved Blades

Abstract Results are presented on an analytical study of the flow field existing upstream of a blade row, where the axial flow is subsonic and the relative flow is supersonic. The flow model used as a basis for the calculations assumes isentropic flow, and considers the case where the suction surface is a circular arc in the entrance region. The results clearly show the unique dependence of the flow through a blade row upon the geometry of the entrance region. Using the results, the complete flow field in the entrance region and upstream of the blade row can be constructed easily.
