Weakly nonlinear thermoacoustics for stacks with slowly varying pore cross-sections [PDF]
A general theory of thermoacoustics is derived for arbitrary stack pores. Previous theoretical treatments of porous media are extended by considering arbitrarily shaped pores with the only restriction that the pore cross-sections vary slowly in the ...

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

Thermoacoustic Refrigeration: Short Review
International Journal of Thermal and Environmental Engineering, 2022 Thermoacoustic is the science that studies the conversion of the heat into acoustical sound and vice versa. The conversion of heat to acoustic power is done through Thermoacoustic engine (TAE). This generated acoustic power can be converted to another and useful form such as mechanical or electrical energy.

Food Science &Nutrition, Volume 13, Issue 11, November 2025.The study developed a continuous thermosonication system (CTS) for the sustainable pasteurization of orange and dried black lime juices. CTS reduced energy consumption by 30% compared to traditional pasteurization while preserving physicochemical, sensory, and microbiological quality.

Thermoacoustic refrigeration systems: recent developments [PDF]
Proceedings of the 3rd International Workshop on Thermoacoustics, 2015 Introduction In this paper, we first review our recent experimental and computational studies on the orificetype [1] and inertance-type [2] pulse tube refrigerators along with related optimization studies. The experimental studies are done at various values of mean pressure of helium (~ 0.35 MPa to 2.2 MPa), different amplitudes of pressure ...
