Numerical Simulation of a Thermoacoustic Refrigerator

Journal of Computational Physics, 1996
A low Mach-number compressible flow model for the simulation of acoustically driven flow in a thermoacoustic stack is constructed. The model is based on the assumption that the acoustic wavelength is much larger than the characteristic hydrodynamic lengthscale.

Review of Thermoacoustic Refrigeration. Description of a Simple Thermoacoustic Refrigerator for Demonstration Purpose.

, 1999
It is possible to build refrigerators using acoustic waves to pump heat. This technique is called thermoacoustic refrigeration and is based on the interac¬tion between pressure oscillation and temperature oscillation of a gas.

DESIGN AND ANALYSIS OF THERMOACOUSTIC REFRIGERATOR

International Journal of Air-Conditioning and Refrigeration, 2013
This paper deals with the design and analysis of a quarter-wavelength, 10 W capacity, thermoacoustic refrigerator using short stack boundary layer approximation assumptions. The effect of operating frequency on the performance of the refrigerator is studied using dimensional normalization technique.

Weakly nonlinear thermoacoustics for stacks with slowly varying pore cross-sections

, 2009
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 ...
