Three-Dimensional Effects of Unsteadiness on Separated Turbulent Flows.
Abstract
A series of experiments is undertaken to take advantage of previous work and state-of-the-art experimental investigate techniques to provide information on a wide class of unsteady flows. Primary objectives of the program are to answer basic questions concerning the effects of unsteadiness on the subject flows and to provide data in a form which is useful to theoreticians and numerical analysts. The ultimate goals of this project include providing the engineering designer of various devices which involve unsteady flow and separation with the tools of conceptual mechanisms as well as a bank of useful data. Key mechanisms which have already been discovered suggest that large scale structures caused by flow unsteadiness exhibit gradual phase shift with increasing frequency of oscillation and that they convect with faster relative speed in attached shear layers As compared to their speed in separated layers.
