Turbulent Vortex Flows.

Abstract

This report presents the results of mean and fluctuating velocity measurements in three types of longitudinal vortex imbedded in turbulent boundary layers in nominally-zero pressure gradients. Vortex generators were installed upstream of the wind tunnel contraction, so that the vortices entering the working section did not have large associated total-pressure wakes. Measurements include all three components of mean velocity, all second- and third-order (and a few fourth-order) mean products of fluctuating velocities, and surface shear stress, all for at least two streamwise positions for each configuration. Temperature-conditioned sampling measurements, and some flow visualization results, were also acquired. (Author)
