Abstract Based on the estimation of thermophysical properties of binary noble gas fluids, He-Ar mixtures are used as working fluids to improve the performance of a pulse tube refrigerator driven by a thermoacoustic engine. Computed and experimental results are reported in detail, and some discussion is given. With 20% molar fraction of Ar the refrigeration temperature was lowered by 3 K as compared to pure He.
