A high performance thermoacoustic Stirling-engine [PDF]
, 2011 In thermoacoustic systems heat is converted into acoustic energy and vice versa. These systems use inert gases as working medium and have no moving parts which makes the thermoacoustic technology a serious alternative to produce mechanical or electrical power, cooling power, and heating in a sustainable and environmentally friendly way.

The use of parallel-plate regenerators in thermoacoustic-Stirling engines
The Journal of the Acoustical Society of America, 2001The regenerator is a key element in a thermoacoustic-Stirling engine. Typically, it is made by stacking up many layers of fine-mesh stainless-steel screen. With a high heat capacity and a typical pore size much smaller than the thermal penetration depth, it provides a nearly isothermal environment at the acoustic frequency.

Development of High Efficiency Linear Alternator for Stirling and Thermoacoustic Engines
6th International Energy Conversion Engineering Conference (IECEC), 2008Because a free piston Stirling engine (FPSE) has no mechanisms such as cranks and cams, high system efficiency can be expected when compared with conventional engines. The output power of the working gas is directly used as the linear alternator input and then converted into electrical power.

Evaluation of thermal efficiency and energy conversion of thermoacoustic Stirling engines
Energy Conversion and Management, 2010Abstract Thermodynamic cycle transferring heat and work was executed in thermoacoustic engines, when the acoustic resonators substituted the moving mechanical components of the traditional heat engines. Based on the traveling-wave phasing and reversible heat transfer, thermoacoustic Stirling engines could achieve 70% of the Carnot efficiency ...

Hydrogen/Oxygen Propellant Densifier Thermoacoustic Stirling Heat Engine
AIP Conference Proceedings, 2004A unique, patent pending, thermoacoustic propellant densifier for the simultaneous densification of hydrogen and oxygen propellants for aerospace vehicles is introduced. The densifier uses a high‐pressure amplitude, low‐frequency Thermoacoustic Stirling Heat Engine (TASHE) coupled with a uniquely designed half‐wave‐length resonator to drive a pulse ...
