Acoustic-structure interaction ASI problems require modeling elastic waves in solids, pressure waves in fluids, and the interaction between the two. Uses of ASI include devices that generate, scatter, transmit, or receive sound and mechanical systems for sound distribution, insulation, or noise cancellation. Acoustic behavior in different types of materials is described by different governing equations. Elastic waves in solids, also called solid vibrations, are a subset of structural mechanics and are therefore modeled using a structural mechanics physics interface. Among the available interfaces for structural analysis, the ones most often used for vibrations analysis are Solid Mechanics , Shell , and Membrane.

These improvements in performance require a re-examination of the fundamental acoustic and fluid dynamic interactions in the acoustic resonators that comprise a thermoacoustic refrigerator. A comprehensive research program of the pulse tube thermoacoustic refrigerator PTR and arbitrarily shaped, circular cross-section acoustic resonators was undertaken to develop robust computational models to design and predict the transport processes in these systems. This effort was divided into three main focus areas: a studying the acoustic and fluid dynamic interactions in consonant and dissonant acoustic resonators, b experimentally investigating thermoacoustic refrigeration systems attaining cryogenic levels and c computationally studying the transport processes and energy conversion through fluid-solid interactions in thermoacoustic pulse tube refrigeration devices. To investigate acoustic-fluid dynamic interactions in resonators, a high fidelity computational fluid dynamic model was developed and used to simulate the flow, pressure and temperature fields generated in consonant cylindrical and dissonant conical resonators.
