Detailed Boundary Layer Measurements on a Transonic Turbine Cascade [PDF]
Journal of Turbomachinery, 1990 The boundary layers of a transonic turbine blade have been measured in detail. The full velocity profiles have been measured at a number of stations on both the suction and pressure surfaces, at conditions representative of engine operation, using a Pilot traverse technique and a large-scale (300 mm chord) linear cascade.
