Influence of Working Conditions on Parameters of Thermoacoustic Engine with Travelling Wave
Archives of Acoustics, 2020 Thermoacoustic converters are devices for direct conversion of acoustic energy into thermal energy in the form of temperature difference, or vice versa – for converting thermal energy into an acoustic wave.

Design of a Mechanical Resonator to Be Coupled to a Thermoacoustic Stirling-Engine [PDF]
ASME 2010 3rd Joint US-European Fluids Engineering Summer Meeting: Volume 2, Fora, 2010 This paper describes the design of a mechanical resonator for a thermoacoustic Stirling-engine. The engine was previously run with a quarter-wavelength acoustic resonator. The advantage of the mechanical resonator is that it is compact and would dissipate less acoustic power.

Mover guide in a linear electric generator with double‐sided stationary stators
The Journal of Engineering, Volume 2019, Issue 17, Page 3986-3990, June 2019., 2019 This study addresses double‐sided stationary stators in a linear electric generator with similar operation to a linear oscillatory motion electric machine. The plate mover in the linear electric generator's double‐sided stationary stators is powered by the acoustic power output of the thermoacoustic engine's acoustic line.

Energy Harvesting with Piezoelectric Element Using Vibroacoustic Coupling Phenomenon
Advances in Acoustics and Vibration, Volume 2013, Issue 1, 2013., 2013 This paper describes the vibroacoustic coupling between the structural vibrations and internal sound fields of thin structures. In this study, a cylindrical structure with thin end plates is subjected to the harmonic point force at one end plate or both end plates, and a natural frequency of the end plates is selected as the forcing frequency.

Thermodynamics Performance Analysis of Solar Stirling Engines
International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 This paper provides numerical simulation and thermodynamic analysis of SOLO 161 Solar Stirling engine. Some imperfect working conditions, pistons′ dead volumes, and work losses are considered in the simulation process. Considering an imperfect regeneration, an isothermal model is developed to calculate heat transfer.
