摘要
利用数值方法模拟了高频微型同轴脉冲管制冷机内部气流交变流动和换热过程。给出了小孔型，双向进气型和多路旁通型脉冲管制冷机内部气流动态参数的瞬态变化。分析了各动态参数变化对制冷机整机性能的影响。
A numerical model for simulating the oscillating flow characteristics in a high frequency miniature pulse tube refrigerator was developed.Instantaneous gas temperature,mass flow rate and pressure were given in this paper.The effects of the orifice,double inlet and multi bypass valves on the performance of the miniature pulse tube refrigerator were also discussed.
