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.

High-Power Thermoacoustic Stirling Heat Engine Results
9th Annual International Energy Conversion Engineering Conference, 2011We are developing a thermoacoustic Stirling heat engine (TASHE) to drive a pulse tube refrigerator (PTR) and electrical linear alternator for instrument cooling and power generation on a Venus lander. The TASHE will produce acoustic (PV) power and deliver it both to the linear alternator to generate electrical power and to the PTR to generate ...

Modeling, construction, and testing of a diaphragm thermoacoustic Stirling engine
Energy Conversion and Management, 2021Abstract In this article, a diaphragm thermoacoustic Stirling engine is modeled, constructed, and tested. First, the working principle of the thermoacoustic system is justified based on a new nonlinear lumped mechanical model. Then, the existence of a stable limit cycle in the nonlinear dynamic response of the engine is predicted using the proposed ...

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.

4 kW Power Thermoacoustic Stirling Heat Engine Test Results
11th International Energy Conversion Engineering Conference, 2013A Thermoacoustic Stirling Heat Engine (TASHE) that produces 4 kW of acoustic power is being developed to drive a pulse tube refrigerator (PTR) for instrument cooling and a linear alternator for power generation on a Venus lander. This duplex system is expected to be highly efficient and has no moving parts at high temperature, improving reliability ...

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

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 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.

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 ...
