Using a side-branched volume to tune the acoustic field in a looped-tube travelling-wave thermoacoustic engine with a RC load [PDF]
Travelling-wave thermoacoustic engine utilises a compact acoustic network to obtain a right time-phasing between the acoustic velocity and pressure oscillations within the regenerator to force gas parcels to experience a Stirling-like thermodynamic cycle.

A coupling model of the PTR by using REGEN and DeltaEC is built for investigating the effects of the cold‐end temperature and cold load on the cooling efficiency. Some experiments are performed on a PTR working at different cold‐end temperature and cold load which are in good agreement with the simulation results.

Thermoacoustic refrigeration for space applications
A 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,
