Numerical optimization of a novel thermoacoustically driven thermoacoustic refrigerator
The Journal of the Acoustical Society of America, 1997Previous 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, 2000The 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 ...
