Experimental studies on thermoacoustic refrigeration

The Journal of the Acoustical Society of America, 1996
Thermoacoustic refrigeration phenomena in a resonance tube were studied experimentally. A horizontal brass tube of 400 mm in length and 40 mm in diameter was closed at one end and attached to the acoustic driver (audio speaker) at the other end. Atmospheric air was enclosed in the tube as a working fluid.

Thermoacoustic–Stirling model refrigerator

The Journal of the Acoustical Society of America, 2001
The design and performance of a model refrigerator that uses a stainless-steel woven regenerator (4.1 cm diameter, 5.0 mm thick) and an unconventional Helmholtz resonator to provide proper phasing for the regenerator are described. Cooling is produced in air at atmospheric pressure with sound pressures in excess of 6 kPa in a transparent 60 cm long ...

Numerical optimization of a novel thermoacoustically driven thermoacoustic refrigerator

The Journal of the Acoustical Society of America, 1997
Previous modeling work on a novel heat-driven refrigerator has generated overall COP numbers in the range of 0.45 using pure helium gas. The modeled conditions are for commercial or air-conditioning cooling temperatures, with a hot drive temperature of 400 °C.

Streaming in thermoacoustic engines and refrigerators

AIP Conference Proceedings, 2000
The efficiency of thermoacoustic engines and refrigerators is now approaching 40% of the ideal efficiency allowed by the laws of thermodynamics. To achieve such high efficiency requires understanding and control of streaming. Sometimes, thermoacoustic phenomena cause unwanted streaming-driven convection of heat, which we strive to eliminate; in other ...
