双入口阀和惯性管是脉冲管制冷机的两种主要移相器。它们对于脉冲管制冷机获得合适的压力与质量流的相位关系至关重要。在过去的几十年里,人们对这两种移相器的独立功能给予了很大的关注,而本研究将尝试研究它们的耦合功能。本文首先用数值方法研究了双入口阀对惯性管冷却性能和特性的影响。然后建立了实验装置来验证数值结果。通过数值和实验研究,得出了由于湍流的存在,惯性管不能为小冷却功率的脉冲管制冷机提供最佳阻抗的结论。在这种情况下,双入口阀可以帮助提供更好的阻抗,进一步提高冷却性能。另一方面,对于冷却功率较大的脉冲管制冷机,惯性管可以提供最佳的阻抗,在这种情况下不需要双进口。
The double-inlet valve and inertance tube are the two main phase shifters of pulse tube refrigerators. They are crucial for the pulse tube refrigerators to obtain an appropriate phase relationship between pressure and mass flow. In the past decades, much attention has been given to understand the separate functions of the two phase shifters, and the present work will try to investigate their coupling functions. In this paper, the influence of the double-inlet valve on the cooling performance and characteristics of inertance tubes are numerically studied at first. Then an experimental setup is built to prove the numerical results. Based on the numerical and experimental study, it is concluded that the inertance tube cannot provide the optimum impedance for those pulse tube refrigerators with small cooling power because of turbulent flow. In such case, the double-inlet valve can help to provide a better impedance and further improve the cooling performance. On the other hand, the inertance tube can provide the optimum impedance for those pulse tube refrigerators with large cooling power and the double-inlet is not necessary in such a case.
