| Research Abstract |
A multistage thermoacoustic engine that can lower the critical onset temperature was suggested recently. However, a multistage thermoacoustic engine that uses multiple regenerators needs installation of regenerators not only at the peak of acoustic impedance distribution in real part, and therefore is generally inefficient. In this report, we determined the configuration of the multistage thermoacoustic engine by numerical calculation, and then examined its efficiency when the temperature of the prime mover was changed. The result shows that low temperature drive and high efficiency can both be achieved with a multistage thermoacoustic engine.
