Using a side-branched volume to tune the acoustic field in a looped-tube travelling-wave thermoacoustic engine with a RC load [PDF]
, 2017 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.

Jet pumps for thermoacoustic applications: design guidelines based on a numerical parameter study [PDF]
, 2015 The oscillatory flow through tapered cylindrical tube sections (jet pumps) is characterized by a numerical parameter study. The shape of a jet pump results in asymmetric hydrodynamic end effects which cause a time-averaged pressure drop to occur under ...

Jurnal Teknologi, 2012 Kertas kerja ini memperkenalkan teknologi terbaru dalam kuasa bendalir iaitu termoakustik, fenomenon yang disebabkan oleh interaksi pepejal-bendalir. Secara umumnya, termoakustik boleh dibahagi kepada dua kategori. Kategori pertama ialah enjin haba, di mana kuasa akustik dapat dijana hasil daripada gelombang yang wujud disebabkan oleh perbezaan ...

Liquid metal thermoacoustic engine [PDF]
The Journal of the Acoustical Society of America, 1986 A liquid metal thermoacoustic engine is studied both theoretically and experimentally. This type of engine promises to produce large quantities of electrical energy from heat at modest efficiency with no moving parts except the acoustic oscillations in the liquid metal.

Demonstration of flywheel-based travelling-wave thermoacoustic engine [PDF]
E3S Web of Conferences, 2021 We report test results on a thermoacoustic engine having a piston-crank-flywheel assembly. The engine maintained steady rotation states when the heating temperature was increased more than 114°C.
