Zusammenfassung: | The effect of the aerofoil suction side curvatures on the 2-D transonic turbine cascade performances is investigated by the numerical and the experimental methods. The Modified FLIC method is used to predict the cascade flows. The experiments are conducted in the wide range of the exit Mach number M2th=0.5 to 2.0 by the optical and the wake traverse methods using the suction-type shock tunnel and the blow-down type wind tunnel. The characteristics of the flow patterns around these four kinds of aerofoil sections are clarified and it is shown that the relation between energy loss and its exit Mach number clearly depends on their suction side curvatures. |
