Berechnung der Druckverteilung von ebenen Schaufelgittern mit stark gewölbten Profilen

In the course of systematic investigations on two-dimensional cascade flow, which have been conducted at the Institute of Fluid Mechanics of the Engineering University of Braunschweig, pressure distributions and angles of outflow have been calculated for two turbine cascades with highly cambered blades, at five different angles of inflow each. The method used is that of conformal mapping due to W. Traupel. The theoretical results have been compared with experiments. Theoretical and experimental pressure distributions are in good agreement. For the angle of outflow the effect of viscosity is not negligible and, therefore, the agreement of theoretical and experimental results is not as good as for the pressure distributions.
