Abstract
A high-speed cascade wind tunnel at the German Aerospace Center (DLR) is used for detailed secondary flow investigation in a transsonic environment. The cascade consists of five NACA65 vanes of 40mm chord length at Mach number 0.67 and Reynolds number of 560.000. Secondary flow control is used in the cascade with passive crosswise mounted fences on the side walls as well as classic boundary layer suction through the walls. In the passive contol case, the coefficient is decreased by 10%. This corresponds to a stage efficiency gain of 0.5%. In the suction case the total pressure loss coefficient can be reduced by 38%, using a mass flow rate of 5% for suction. Local total pressure loss coefficients are calculated and the integral total pressure loss is determined using a wake rake. Evaluation plots of oil streak measurements, five hole probe and a stereo-PIV measurements are compared with regard to their degree of information.
