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.
