Integrated Experimental System for Turbulent Flow-Elastic Surface Interactions.
Abstract
The overall goal of this investigation is to design, acquire and implement components that form an integrated system for detecting the instantaneous structure of unsteady and turbulent flows, in conjunction with elastic motions of an adjacent surface. Central to this technique is use of a high powered Argon ion laser that scans through space at time scales orders of magnitude smaller than the characteristic time scale of the flow. This approach provides the basis for two dimensional and three dimensional scans of complex flows. The instantaneous deflection of the surface is to be acquired by a video zoom technique or, alternately, a speckle technique. Quantitative evaluation of the images acquired using this approach involve the use of critical point theory, in conjunction with flow topological techniques and pressure source representations of the unsteady flow. These techniques require the instantaneous, global features of the flow.
