Concerns about global warming, pollution and the depletion o f ozone layer due to CFC refrigerants have urged researchers to find alternatives to conventional engines and refrigerators. Some recent advancement in the field of thermoacoustics have revolutionized the way many conventional devices operate. Thermoacoustics deals with the conversion of heat into sound energy and vice versa. A heat-driven thermoacoustic refrigerator (HDTAR) can be considered as a new source o f renewable energy with no moving part and no hazardous materials. A HDTAR is comprised o f a thermoacoustic heat engine which converts heat into acoustic work and a thermoacoustic refrigerator which utilizes this acoustic work as an input to produce refrigeration. Thus, by applying this technology, any source o f heat particularly the industrial waste heat could b
