The final goal of the studies is to accomplish drastic reduction of cost and weight of aeroengines by minimizing total number of the LPT (Low Pressure Turbine) blades. One big hindrance against the accomplishment of this goal is the occurrence of flow separation on the blade suction surface, ending up with the deterioration of the aerodynamic performance of the turbine blades. As a countermeasure to avoid large-scale flow separation, usage of wakes from upstream blades is now being explored. Experimental studies using a single hot-wire probe are then executed to make detailed investigation of the flow over the suction surface of a high-lift LPT linear cascade, which is subjected to the passing of wakes from moving bars, at low Reynolds number conditions. Total pressure measurements downstream of the cascade as well as static pressure measurements on the blade surface are also made.
