摘　　要：建立了一套实验装置 ,系统地考察了气波机接受管端部加入蓄冷填料 ,由反射激波强度削弱所引起的制冷效率的影响程度。理论上初步建立了管内非定常流动数学模型 ,对接受管内激波的流动进行了数值模拟 ,计算结果与实验测量值趋势相同 ,可为气波制冷机的改造。An experimental equipment was set up.The influent extent of refrigerating efficiency caused by the weakening of reflected shock wave intensity was studied systematically with cold-saving packing added in the end section of the accepting tube.The mathematic model of non-constant flow in tube was established theoretically,and the shock wave flow in the accepting tube was simulated.The trend between the calculation results and those experimental ones agreed,which can be used as a theoretical direction for the reforming,designing and optimizing of wave machines.
