C08 Influence of a variable acoustic load on Traveling-Wave Thermoacoustic Engine

Abstract

A thermoacoustic engine has attracted attention because it can work without moving parts and use variety of heat sources. When the thermoacoustic engine receives heat from a hot heat source,, the gas inside it spontaneously oscillates and outputs acoustical energy. In general, this acoustical energy is converted into electrical energy or cold energy by the thermoacoustic coolers or linear alternators. The performance of the engine depends on the acoustic-to-heat or -electric converter. In this study, we characterized the converter consists of a tank and a valve, and constructed the traveling-wave thermoacoustic engine with the characterized converter. The measurements of the performance were shown.
