A cascade thermoacoustic engine

The Journal of the Acoustical Society of America, 2003
A cascade thermoacoustic engine is described, consisting of one standing-wave stage plus two traveling-wave stages in series. Most of the acoustic power is produced in the efficient traveling-wave stages. The straight-line series configuration is easy to build and allows no Gedeon streaming.

Cascade thermoacoustic engine

The Journal of the Acoustical Society of America, 2003
Over the past several years, Los Alamos has successfully fabricated and tested traveling wave thermoacoustic heat engines having efficiencies much greater than those of traditional standing wave thermoacoustic engines. Unfortunately, Gedeon streaming effects present in these traveling wave engines has required using fluid flow ‘‘diodes’’ having greater
