摘要
通过实验本文研究了气波制冷机工作管充气时间,分界面混合效应以及工作管内反射激波等因素对气波制冷效率的影响,并结合管内流动波图对实验结果进行了分析,提出了采用激波吸收腔缩短工作管长,消除反射激波,提高制冷效率的方法。
The effects of shock tube opening times,interface mixing,and reflected shock waves on the refrigeration efficiency are studied bymeans of experiments.Simplified wave diagrams are constructed whichprovide schemes to analyze the experiments.In the case of a short tubes,a cylindrical tank attached to the end of the shock tube can prevent thedriver gas from being heated by the reflected shock wave,and thusincrease the refrigeration efficiency.
