A miniature thermoacoustic stirling engine
Energy Conversion and Management, 2008A miniature thermoacoustic stirling engine was simulated and designed, having overall size of length 0.65 m and height of 0.22 m. The acoustic field generated in this miniature system has been described and analyzed. Some efforts had been paid to coupling and matching, and a miniature thermoacoustic engine and some extra experimental components have ...

Design and optimization of a cascade thermoacoustic Stirling engine
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2013This article deals with the design and optimization of a cascade thermoacoustic Stirling engine. Different configurations for cascade thermoacoustic Stirling heat engine are investigated. A simplified model is proposed to enable initial design guidelines. The most important characteristics of the cascade system are examined.

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.

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%.

Output characteristics of Stirling thermoacoustic engine
Energy Conversion and Management, 2008Abstract A thermoacoustic engine (TE), which converts thermal energy into acoustic power by the thermoacoustic effect, shows several advantages due to the absence of moving parts, such as high reliability and long lifetime associated with reduced manufacturing costs. Power output and efficiency are important criteria of the performance of a TE.

The performance of a high-frequency thermoacoustic-Stirling engine
The Journal of the Acoustical Society of America, 2003A thermoacoustic-Stirling engine that operates at 400 Hz with a working fluid of 1-MPa helium is constructed. For proper acoustic phasing in this engine’s regenerator, an acoustic power feedback path exists in the form of an annulus surrounding the regenerator. This feedback path is obtained by suspending an insulated, stainless steel sleeve containing

A pistonless Stirling engine—A new direction in thermoacoustics
The Journal of the Acoustical Society of America, 1999Due to its thermodynamic reversibility, the Stirling cycle has an inherent advantage in thermal efficiency over the standard, irreversible standing-wave thermoacoustic cycle. The main disadvantage of the Stirling cycle has been the need for high-pressure, sliding piston seals. Building significantly on the ideas of Ceperley [J. Acoust. Soc. Am.

Study of a thermoacoustic-Stirling engine connected to a piston-crank-flywheel assembly
The Journal of the Acoustical Society of America, 2021This paper deals with the theoretical description of self-sustained oscillations resulting from the coupling of a piston-crank-flywheel assembly with a thermoacoustic-Stirling prime mover. The governing equations of the piston-flywheel motion are coupled to those of the thermoacoustic system, which is described in the time domain through a rational ...

Ultrasonics, 2006
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.

A numerical simulation method and analysis of a complete thermoacoustic-Stirling engine
Ultrasonics, 2006Thermoacoustic prime movers can generate pressure oscillation without any moving parts on self-excited thermoacoustic effect. The details of the numerical simulation methodology for thermoacoustic engines are presented in the paper. First, a four-port network method is used to build the transcendental equation of complex frequency as a criterion to ...
