Abstract
Linearized model of the acoustic characteristics in a resonance-tube refrigerator was developed with taking into account the fluid friction and the heat transfer at the wall. The validity of the model was examined through the comparison with experimental results obtained under various system parameters including resonance-tube configurations, the position of the stack and thermophysical properties of working fluids. The resonance frequency is well predicted by introducing a correction factor on the inertance at the open end of the tube. This correction factor was a function of the tube configuration and the position of the stack, and was determined independently on thermophysical properties of the fluid. The amplitude and the phase of the acoustic pressure showed qualitative agreement with the experimental data.
