Abstract
The complexity of high Reynolds number turbulent flows facilitates the need for low dimensional approaches to develop an understanding of important flow phenomena. Many times the important flow physics is associated with the organized coherent motions buried in complex turbulent shear layers. While the identification of these turbulent structures has been studied for quite some time the importance of understanding the dynamics of these organized structures have been of high interest in the community recently. This has been exaggerated as the desire to control fluid systems and has gained a more important role in the community. This talk will discuss applications of techniques for identifying coherent structures from experimental data sets in boundary layers, cavity flows and wall jets. The focus of the applications will be to identify the dynamics of these structures as related to drag and noise production such that flow control can be efficiently applied.

Biography
Lawrence Ukeiley is an Associate Professor of Mechanical and Aerospace Engineering at the University of Florida. He received a B.S. degree in Mechanical Engineering from Alfred University and M.S. and PhD from Clarkson University. He held research positions at BEAM Technologies, NASA Langley Research Center, and the National Center for Physical Acoustics at the University of Mississippi before joining the University of Florida. His laboratory (Unsteady Fluid Dynamics Group) is part of the Florida Center for Advanced Aero Propulsion (a 4 university Florida State Center of Excellence) where he serves as an Associate Director. His research is concentrated in fluid dynamics and aeroacoustics where his group works on fundamental understanding of fluid physics and the control of the phenomena. Projects in his group have ranged from low speed applications associated with Micro Air Vehicles to supersonic flows exhausting from jets or over cavities.
