Abstract

The preliminary results of two experiments on low Reynolds number turbulent boundary layers are presented. The first experiment was a flat plate zero pressure gradient flow while the second experiment studied the flow over a two-dimensional circular arc profile of thickness-to-chord ratio 0.326. Both experiments showed some discrepancies in the momentum integral balance which have not yet been satisfactorily resolved. The turbulence intensities on the flat plate displayed remarkable inner' and outer' flow scaling. The effects of pressure gradient and convex curvature on the circular arc profile had a strong effect on the turbulence intensities and no simple scaling could be discerned in this case.
