Synchronized acoustic refrigerator and heat engine (SARAH)

Abstract

In light of the present global energy scenario, it is imperative to seek novel and efficient energy solutions to redress the situation. Solar energy, wind energy, geothermal energy, ocean thermoclines and waste heat recovery are the major players in the sustainable energy field. In this paper we propose a Synchronized Acoustic Refrigerator And Heat Engine (SARAH), a Thermoacoustic (TA) device capable of harnessing these untapped sources in a cost-effective and efficient way on both small and large scales. It is a coupled device which transforms acoustic power into heat (refrigerator or heat pump) and heat into acoustic power (engine or primemover).
