Thermoacoustics With Multiple-Phase Working Fluids

Abstract

A one year effort to improve the understanding of thermoacoustic engines and refrigerators using multiple-phase working fluids resulted in a more complete. The specific system considered was an inert gas-condensing vapor mixture in a cylindrical pore with wet walls. It was found that vapor diffusion effects in the mixture are analogous to the heat diffusion effects in the thermoacoustics of inert gases, and that these effects can be expressed in terms of the thermoacoustic viscous function used in the theory of sound propagation of constant cross-section tubes. This theory was reduced to a concept for a practical device. This technical report in contained, for the most part, in two papers published in the Journal of the Acoustical Society of America which are a part of this report and a patent also included here.
