“…A good regenerator material should have a large volumetric specific heat compared to that of the working gas. The C p of lead, usually used as cryocooler martial, rapidly decreases in low temperature region and is not suitable for the cryocooler martial below 15 K. The Er 3 Ni is commercial used low-temperature cryocooler material below 15 K [22], but its C p peak is narrow as shown in Fig. 2.…”

“…Figures 7 and 8 show the comparison of the cooling power predicted by the proposed model with the theoretical data from reference [5] and experimental results [1,6] for the first and second stages, respectively. The predictions are in good agreement with the experimental and theoretical data for temperatures below 4 K. However, deviations are observed above this temperature perhaps due to the fact that all the loss factors in the system (especially axial heat conduction loss) are not fully accounted for.…”

A numerical modelling technique for predicting the detailed performance of a double-inlet type two-stage pulse tube refrigerator has been developed. The pressure variations in the compressor, pulse tube, and reservoir were derived, assuming the stroke volume variation of the compressor to be sinusoidal. The relationships of mass flowrates, volume flowrates, and temperature as a function of time and position were developed. The predicted refrigeration powers are calculated by considering the effect of void volumes and the phase shift between pressure and mass flowrate. These results are compared with the experimental results of a specific pulse tube refrigerator configuration and an existing theoretical model. The analysis shows that the theoretical predictions are in good agreement with each other.

“…It was also used by Mahkamov 43 in what appears to be the first full three-dimensional simulation, but details are embargoed. Also, in the related business of cryocooler modeling it has been used with reasonable success on simplified problems 77,78,79,81,82,83,84,85,86,87,88 And this report has utilized it to provide a detailed axisymmetric simulation.…”
