Abstract : The secondary flow in a developing boundary layer of a square duct is investigated experimentally. Measurements of the horizontal components of secondary flow were made for three free stream Reynolds numbers based upon the hydraulic diameter of 360,000, 720,000, and 1,400,000. Measurements of the developing boundary layer parameters and turbulence quantities in a corner were made for the intermediate Reynolds number. A criterion for two dimensionality of wind tunnel flow is examined and a correction for three dimensionality is evaluated from the experimental data. (Author)
