Higher Order Turbulence Results for a Three-Dimensional Pressure-Driven Turbulent Boundary Layer.

Abstract

Triple and fourth-order turbulence products obtained from coincident fine-spatial-resolution three-velocity-component laser-Doppler-anemometer measurements are presented for a three-dimensional pressure-driven turbulent boundary layer from y(+)>3 to the outer edge in local wall-shear-stress-direction co-ordinates. The wind tunnel flow is produced by a Re(theta) = 5940, U(ref) = 27.5 m/s, upstream turbulent boundary layer on a flat surface that approaches a wing-body junction, although no results near the junction vortex are presented. For most of the presented locations, the mean velocities and stresses from this data set were previously discussed by Olcmen and Simpson (1995a). New data at additional locations and for a mean two-dimensional flow are presented. Results are plotted in 6 different co-ordinate systems in Appendices A-F.
