Abstract: | Experiments were conducted in a turbulent boundary layer near separation along a flat plate. The pressure gradient in flow
direction was varied such that three significant boundary layer configurations could be maintained. The flow in the test section
thus had simultaneously a region of favourable pressure gradient, a region of strong adverse pressure gradient with boundary
layer separation and a region of reattached boundary layer. Specially designed fine probes facilitated the measurements of
skin friction and velocity distribution very close to the wall. Bulk flow parameters such as skin friction coefficient C
f, Reynold's number Reδ2 and shape factors H and G, which are significant characteristics of wall boundary layers were evaluated. The dependence of these parameters on the
Reynolds number and along the test section was explored and the values were compared with other empirical and analytical formulae
known in the literature. |
