计算了Delpuech和Lacaze等的致冷机(以下简称为D-L致冷机)的致冷功率(作为频率和磁化场的函数),结果与D-L致冷机的实验相符.按照本文提出的方法计算了膜沸腾产生所对应的频率,在四个不同的磁化场条件下所得结果与实验符合较好.进而计算了循环过程的S-T图以及致冷效率.所有计算结果表明,我们将具体问题模型化的手段是合理的.运用这些手段,讨论了采用圆筒式磁元件及采用烧结钆镓石榴石工质的可行性. The refrigeration power (as a function of frequency and magnetizing field) for refrigerators Delpuech and Lacaze, etc. (hereafter referred to as DL refrigerators) was calculated and the results were in agreement with the experiment of the DL refrigerator.According to the method proposed herein, The results of the four different magnetization fields agree well with the experimental results, and then the ST diagram and the cooling efficiency of the cycle are calculated. All the results show that we model the specific problems Means are reasonable.Using these methods, the feasibility of using cylindrical magnetic components and sintered gadolinium gallium garnet working fluid is discussed.
