| 摘 要： | 脉冲管制冷机内部工质气体热力学循环是理解脉冲管制冷机制冷机理的一个重要方面。本文采用拉格朗日方法对制冷机蓄冷器内部气体微团热力学循环进行了数值统计分析，结果表明，对于变频率和充气压力工况，蓄冷器内单位质量气体单位时间内循环换热量和制冷机能达到的最低制冷温度紧密相关。

| Abstract: | Thermodynamic cycles are very important and useful for understanding the mechanism of the pulse tube refrigerator.In this paper,two-dimensional axi-symmetric simulations of an inertance tube pulse tube refrigerator are conducted,and thermodynamic cycles of the gas parcels oscillating in regenerator are studied and analyzed in the Lagrangian's regime.The results show that the lowest temperature of the system is possibly decided by the amount of heat pumping by thermal cycles under different frequencies and c... |
