An experimental thermoacoustically driven thermoacoustic refrigerator
The Journal of the Acoustical Society of America, 1996The construction of a thermoacoustically (heat) driven, thermoacoustic refrigerator (TADTAR) is nearing completion. The design utilizes a novel resonator topology and high-efficiency primary heat exchangers. Numerical models suggest a cooling power level of at least 500 W over a temperature span of 40 °C.

A cascade thermoacoustic engine
The Journal of the Acoustical Society of America, 2003A 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.

Improvements in an experimental thermoacoustically driven thermoacoustic refrigerator
The Journal of the Acoustical Society of America, 1997A thermoacoustically (heat) driven, thermoacoustic refrigerator apparatus, having a novel topology, has produced significant cooling power and efficiency. It has achieved a cooling temperature span of 60 °C, and 91 W of cooling power at a span of 25 °C, with an overall COP of 0.15. These numbers were produced with a porous carbon refrigerator stack and

SCALING OF THERMOACOUSTIC REFRIGERATORS
AIP Conference Proceedings, 2008The possibility of scaling-down thermoacoustic refrigerators is theor. investigated. Standing-wave systems are considered as well as traveling-wave. In the former case, a ref. system is taken that consists of a resonator tube (50 cm) with a closed end and a PVC stack (length 5 cm).

Thermoacoustic refrigeration for space applications
Space Programs and Technologies Conference, 1991A thermoacoustic refrigerator has been designed, tested, and certified by NASA to be flown aboard the space-shuttle get-away-special (GAS) payload program on STS-42 in January 1992. This thermoacoustic heat pump uses acoustic power to pump heat from a low-temperature source to a high-temperature sink. It has only 15 g of moving mass operating at 400 Hz,
