Experimental Investigation on the Thermoacoustic Effect in Easily Accessible Porous Materials
Energies, 2020 Thermoacoustic devices are the systems which use acoustic power to transport heat through a stack in a resonance tube. The stack is one of the most important parts of the thermoacoustic systems.

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.
