Ultrasonics, 2006
In this paper, a thermally-driven thermoacoustic refrigerator system without any moving part is reported. This refrigeration system consists of a thermoacoustic-Stirling heat engine and a thermoacoustic-Stirling refrigerator; that is, the former is the driving source for the latter. Both the subsystems are designed to operate on traveling-wave mode. In

In this paper, an experimental study of the effect of the resonator shape on the performance of a traveling-wave thermoacoustic engine is presented. Two different resonators were tested in the thermoacoustic-Stirling heat. One resonator is an iso-diameter one, and the other is a tapered one.

Numerical investigation on a thermoacoustic heat engine unit with a displacer
Energy Conversion and Management, 2014Abstract A novel thermoacoustic heat engine – double-acting travelling wave thermoacoustic heat engine has been proposed by our research group recently. It consists of at least three symmetric engine and resonator units and has advantages on efficiency, power density and heat source flexibility.

A thermoacoustic engine capable of utilizing multi-temperature heat sources
Energy Conversion and Management, 2009Low-grade energy is widespread. However, it cannot be utilized with high thermal efficiency directly. Following the principle of thermal energy cascade utilization, a thermoacoustic engine (TE) with a new regenerator that can be driven by multiple heat sources at different temperature levels is proposed.

A thermoacoustic Stirling heat engine
Nature, 1999Electrical and mechanical power, together with other forms of useful work, are generated worldwide at a rate of about 1012 watts, mostly using heat engines. The efficiency of such engines is limited by the laws of thermodynamics and by practical considerations such as the cost of building and operating them.

Unconventional thermoacoustic heat engines
The Journal of the Acoustical Society of America, 2006During 1988 to 1994, John Strachen and Harold Aspden demonstrated an all-solid-state thermoelastic cooler which was 0.5 cm thick and a few centimeters in length. With 7.2 V dc applied across the device, it drew 6.3 W of electrical power and produced 13.7 W of cooling power with a 20<th>°C temperature drop.

A thermoacoustic-Stirling heat engine: Detailed study
The Journal of the Acoustical Society of America, 2000A new type of thermoacoustic engine based on traveling waves and ideally reversible heat transfer is described. Measurements and analysis of its performance are presented. This new engine outperforms previous thermoacoustic engines, which are based on standing waves and intrinsically irreversible heat transfer, by more than 50%.

Geometrical Optimization of Thermoacoustic Heat Engines
49th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2011Thermoacoustics is concerned with the interaction of thermodynamics and acoustics. This interaction can bring numerous innovative applications in power generation and refrigeration. Thermoacoustic phenomenon can be classified into two main categories: the first one where the thermal energy (heat) is transformed into acoustic energy (sound) is called ...
