摘要(Abstract)：

针对气波机振荡管内气体非定常流动特性难以通过实验捕捉、二维数值计算不能完全真实模拟高压气体运动过程等问题，首先进行了双开口气波制冷机三维非定常流动数值计算模型开发，并验证了模型的可靠性；然后研究了振荡管内非定常流场流动特性，并得到了振荡管内多点激励载荷。研究结果表明：振荡管内流体压力波动范围为-15～85 kPa，温度波动范围为249～372 K；振荡管内沿通道高度方向的流体压力和温度分布基本不变，但靠近高压端口的管内流体沿通道长度方向的压力和温度都有较大梯度。研究结果为进一步分析气波机的压力交换制冷机理、振荡管流致振动和延寿提供了技术支持。
For the problems that the unsteady flow characteristics of the gas in the oscillating tube is difficult to be captured through the experiment，the 2D numerical investigation cannot completely simulate the motion process of high-pressure gas，a 3D numerical calculation model of the unsteady fluid of the double-opening gas wave refrigerator(DOGWR) was firstly established，and the reliability of the numerical model was verified.The characteristics of the unsteady flow field in the oscillating tube were studied in details，and the excitation loads at multiple points in the oscillating tube were obtained.The research results show that the pressure fluctuation range of the fluid in the oscillating tube is-15～85 kPa，and the temperature fluctuation range is 249～372 K.The distributions of pressure and temperature of the fluid in the oscillating tube along the height of the channel are basically unchanged，but those of the fluid at the high-pressure port has a large gradient along the length of the channel.The research results provide technical support for further analyzing the pressure exchange refrigeration mechanism，flow-induced vibration of oscillating tube，and life extension of the gas wave refrigerator.
