Using a side-branched volume to tune the acoustic field in a looped-tube travelling-wave thermoacoustic engine with a RC load [PDF]
Travelling-wave thermoacoustic engine utilises a compact acoustic network to obtain a right time-phasing between the acoustic velocity and pressure oscillations within the regenerator to force gas parcels to experience a Stirling-like thermodynamic cycle.

Active control of thermoacoustic amplification in a thermo-acousto-electric engine
International audienceIn this paper, a new approach is proposed to control the operation of a thermoacoustic Stirling electricity generator. This control basically consists in adding an additional acoustic source to the device, connected through a ...

Determination of the stability limit of a thermoacoustic engine by means of finite elements [PDF]
A finite element model is presented to obtain the stability limit of, as an example, 2D standing wave thermoacoustic engine. The stability limit is the required heating to obtain self-sustained (thermo)acoustic oscillations. The method used to obtain the

Thermoacoustic energy conversion is based on the Stirling cycle. But rather than using pistons to create mechanical work, it utilizes sound waves. The most basic design of a thermoacoustic engine utilizes a simple resonance tube in which a regenerative ...

Oscillatory flows in jet pumps: towards design guidelines for thermoacoustic applications [PDF]
Thermoacoustic engines are an interesting alternative to conventional heat engines (such as Stirling engines) due to the absence of moving parts in the hot region and the small temperature difference required to operate.

Conceptual Design of a Small-scale Travelling-wave Thermoacoustic Stirling Cryocooler
Thermoacoustic machines have received increased interest since Sondhauss’ initial investigation into ‘thermoacoustic oscillations’ in 1850, due to their diminished environmental impact, and high reliability from the omission of moving parts.
