摘　　要：双行波热声制冷机因为其内禀的高效率、热驱动及无运动部件的优点,非常有潜力成为常规制冷方式的一种替代技术。为了详细地研究它的工作特点,我们发展了一套较完整的热声模拟程序,可以准确地预测系统工作频率,在一定的误差范围内给出系统的热力性能,并对系统起振的难易程度进行有效的判断。借助于此套程序,我们对行波发动机驱动的行波制冷机进行了数值模拟,主要是对它们之间两种不同的耦合方式(旁通耦合和末端耦合)进行了对比,初步实验结果显示了程序的有效性。Thermoacoustic refrigerator with double Stirling cycles has good potential as an alternative of ordinary refrigeration technology due to intrinsic high efficiency, heat driven mechanism, no moving components inside and environment-friendliness. We have developed a numeric program to simulate its performance, and mainly compare the performance of two different coupling configurations： the bypass coupling and end coupling. Meanwhile during the experiments to verify the calculation, a simple criterion about whether a thermoacoustic system can easily start self-oscillation is also proposed.
