Thermoacoustic Engines in Alternate Geometry Resonators
Abstract
The purpose of the research reported herein is to branch out from thermoacoustics in the plane wave geometry to study radial wave thermoacoustic engines. Specifically, two possible advantages were sought from radial systems: (1) reduction of harmonic generation due to natural anharmonicity of the resonators and (2) improved engine performance using naturally sloped stacks. Results show that the anharmonicity of the resonator significantly reduces non-linear harmonic generation and that sloped stacks significantly improve the refrigerator coefficient of performance in plane wave systems.
