Verification of the applicability of the linearized thermoacoustic theory proposed by Swift, J. Acoust. Soc. Am., 84-4(1988), 1145-1180, to an acoustic-resonance tube refrigerator and discussions on the advanced linearized theory were conducted through a comparison with the measured temperature distribution along the stack in a simulated acoustic-resonance tube. The measured temperature in all cases of various stack configurations such as stack plate-spacing and length showed an almost linear distribution along the stack, while Swift's linearized theory gave a curved distribution with relatively large deviation from experimental data. Eddy diffusivity and/or steady streaming effects excited by sound waves were taken into account in the linearized model, and the effects of these terms on the prediction of temperature distribution were examined. The agreement between the theory and the experiment was markedly improved by the introduction of steady streaming. This provided a guideline for the construction of an advanced linearized theory.
