Some features of strongly accelerated turbulent boundary layers
Abstract
Strongly accelerated turbulent boundary layers are investigated experimentally under different distributions of the acceleration parameter K in order to obtain data on flow structure. Results are given for a flow in which K increases linearly with x to a maximum value, stays constant at this level for a short distance, and then decreases linearly with x. It is shown that the surface skinfriction is not reduced to laminar values in sink flows unless K is greater than 3.6 x 10 to the  6th. In nozzletype flows, K must also be greater than this value over a short distance in order to produce a short relaminarized region downstream.
