Abstract (in Chinese)
藉由參考多篇文獻設計出的史特靈冷凍機之再生器量測機,量測再生器在震盪流下相關特性,工作流體在壓縮、膨脹過程中會通過再生器,因孔質材料會產生壓力差,進而達到預熱預冷之效果。
   實驗首先以200目、300目、400目三種不鏽鋼網目,製成直徑5 mm與長45 mm之再生器。在不同轉速、溫度及填充壓力6bar情況下,共21組實驗,求出再生器最大雷諾數與摩擦係數之關係式及有效度。
   由實驗結果得知400目有最小的雷諾數、最低的摩擦係數及均衡的有效度,故在本實驗中最適合運用在史特靈冷凍機中。
Abstract (in English)
The regenerator measuring machine of Stirling refrigerating machine designed to measure the relevant and important characteristics of the regenerator under the oscillating flow with reference to previous studies. The working fluid will pass through the regenerator during the compression and expansion process and the porous material will produce the pressure drop that can achieve the effect of preheating and precooling.
  In the experiment, three stainless steel meshes of 200 Mesh, 300 Mesh, and 400 Mesh were used to make a regenerator with a diameter of 5 mm and a length of 45 mm. The experiments were performed at different speeds, temperatures and constant filling pressures of 6 bar. Thus a total of 21 sets of experiments were performed to find the relationship between the maximum Reynolds number of the regenerator, the coefficient of friction and effectiveness of regenerator.
  According to the experimental results, 400 mesh has the smallest Reynolds number, the lowest friction coefficient and the effective degree of balance. So it is most suitable to use in the Stirling refrigerator for this experiment.
