Abstract
Boundary layer and free stream measurements were taken at midspan for the first stator of a two-stage low-speed axial research compressor with IGV. The flow pattern on the blade suction surface is described for three different operating points and the transition onset is investigated. Rotor blades were manipulated to exhibit a larger upstream and downstream flow effect and were used to investigate the correlation between downstream wake propagation and upstream potential effect. In this study, these manipulated blades were used to unambiguously identify the potential and wake effects and their propagation in space and time. The wake causes induced transition on the downstream stator. Natural transition occurs between wakes. The amplified potential effect of the manipulated blade propagates upstream even beyond the stator.
