Measurements of the impedance matrix of a thermoacoustic core: Applications to the design of thermoacoustic engines [PDF]
The Journal of the Acoustical Society of America, 2013 The successful design of a thermoacoustic engine depends on the appropriate description of the processes involved inside the thermoacoustic core (TAC). This is a difficult task when considering the complexity of both the heat transfer phenomena and the geometry of the porous material wherein the thermoacoustic amplification process occurs.

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
