Understanding the Interaction of Acoustic Metamaterials and Turbulent Flow
Abstract
A study is proposed of the fundamental physical mechanisms and issues that come into play when metamaterials are used with flow. This work will be a collaboration between faculty and students in the Center for Renewable Energy and Aerodynamic Technology at Virginia Tech and in the Electromagnetic and Acoustic Materials Group at the University of Exeter in the United Kingdom.Goals of the work are to develop and demonstrate metamaterial surfaces optimized for generating surface trapped acoustic waves in the presence of flo"w, to demonstrate control of the surface trapped waves by tailoring the flow/metamaterial interface, and to demonstrate back-action"" of surface trapped modes on the flow structure, as a precursor of employing this as a flow-controlstrategy. The approach which inc"ludes wind-tunnel experiments at Virginia Tech and static acoustic tests at Exeter University will involve a closely coordinated col"laboration, including visits in both directions between the two institutions. This proposal requests funds to meet the costs of the"" work at Virginia Tech, and the costs to both teams of maintaining an effective international collaboration. Core costs of the Exete"r University work will be covered by UK governmentagencies.
