摘要
利用单管式压力波制冷机实验装置，在接收管长度为L=1．5～6m、膨胀比为ε=3～6的范围内，研究了激波吸收器对压力波制冷机制冷效率、转速及峰值激励频率的影响规律。所得结果对压力波制冷机的优化设计有一定参考价值。
The effects of a shock wave absorber on the pefformance of pressure wave refrigerator are investigated experimentally by means of a single- tube experimental setup. In the experiments, the length of the oscillatory tube is from 1.5m to 6m, the expansion ratio is from 2.0 to 6.0.The results show- that the refrigerating efficiency is increased signilicandy, the optimal exciting frequency is decreased by Absorbing the reflected shock wave at the closed end of the oscillatory tube.
