Cascaded Thermoacoustic Devices

Abstract
A thermoacoustic device is formed with a resonator system defining at least one region of high specific acoustic impedance in an acoustic wave within the resonator system. A plurality of thermoacoustic units are cascaded together within the region of high specific acoustic impedance, where at least one of the thermoacoustic units is a regenerator unit.

Application(s)
Acoustic power conversion. Design of thermoacoustic engines and refrigerators.

Advantages
Increased efficiency, reliability and lower fabrication costs for thermoacoustic engines and refrigerators.
