SOME EXPERIMENTS ON EQUILIBRIUM TURBULENT BOUNDARY LAYERS IN FAVORABLE PRESSURE GRADIENTS,
Abstract
A boundary layer wind tunnel in which an arbitrary negative pressure gradient could be developed was designed and built. The effects of selected pressure gradients on boundary layers grown on one of the walls of the tunnel were studied. It was possible to obtain equilibrium boundary layers of the type first suggested by Clauser, that is layers whose non-dimensional velocity defect distribution is invariant along the direction of flow. The velocity defect distributions for two such boundary layers were established, corresponding to values of B of -0.35 and -0.53, where B is Clauser's non-dimensional pressure gradient parameter. These velocity profiles are compared with the profiles predicted by the Mellor-Gibson theory. The agreement between the two is very good. (Author)
