Thermoacoustic Engines and Refrigerators [PDF]
Physics Today, 1995 We ordinarily think of a sound wave in a gas as consisting of coupled pressure and displacement oscillations. However, temperature oscillations always accompany the pressure changes. The combination of all these oscillations, and their interaction with solid boundaries, produces a rich variety of “thermoacoustic” effects. Although these effects as they

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.

Modelling and Simulation in Engineering, Volume 2018, Issue 1, 2018., 2018 This paper describes a numerical model based on discontinuous Galerkin method for thermoacoustic investigation. Numerical investigation was conducted to study the behaviour of thermoacoustic wave propagations induced by thermal effects in 2‐dimensional enclosure. The compressible Navier‐Stokes equations are used as the governing equations.
