Influence of Working Conditions on Parameters of Thermoacoustic Engine with Travelling Wave

Thermoacoustic converters are devices for direct conversion of acoustic energy into thermal in the form temperature difference, or vice versa – converting an wave. In first case, device is called a thermoacoustic heat pump, second engine. can use (or produce) standing travelling This paper describes construction and properties single-stage engine with kind works using Stirling cycle. It uses gas as working medium does not contain any moving parts. The main component regenerator equipped two exchangers. Most commonly, porous material set metal grids used regenerator. An wave created result difference between cold hot exchanger. influence gas, such parameters static pressure at exchanger on engine, primarily its efficiency, was investigated. achieved efficiency up to 1.4% air medium, which coincides values obtained other laboratories. argon equal 0.9%.
