摘要

本實驗模型，藉由參考多篇文獻而設計出史特靈製冷機再生器量測機，可用來量測再生器在震盪流下流體力學相關特性，再生器為孔質材料具有能將熱量儲存的能力，在波紋管壓縮膨脹過程中工作流體通過再生器將能量儲存於其中，可在下次循環釋放熱量來預熱工作流體。
實驗條件為填充壓力6 bar，實驗時間為150 seconds，實驗主要以直徑5 mm、長45 mm、200目、300目及400目三支再生器為主，200目再生器有2組實驗數據，300目再生器有1組實驗數據，400目再生器有3組實驗數據支持，總共實驗數據有6組，每組實驗由25轉至700轉共28個實驗數據，找出其最大壓力梯度與轉速之關係圖、質量流率與最大雷諾數Re_max關係圖及最大雷諾數Re_max與摩擦係數f之關係式Correlation均詳列於實驗結果中。

In this experimental model, the Stirling Cooler Regenerator Measuring Machine is designed by several references , which can be used to measure the Fluid Mechanics characteristics of the regenerator under oscillating flow. The regenerator is a porous material ,with heat storage capability. During the compression process and expansion process of the bellows, the working fluid stores energy in the regenerator, which can release heat in the next cycle to preheat the working fluid.
The experimental conditions are at filling pressure of 6 bar and each experimental time is 150 seconds. The experiment mainly consists of three regenerators of diameter 5 mm, length 45 mm, 200 mesh, 300 mesh and 400 mesh. Regenerator Mesh Number 200 has 2 sets of experimental data. There are 1 sets of experimental data for the Regenerator Mesh Number 300, and 3 sets of experimental data for Regenerator Mesh Number 400. Totally have 6 sets experiment data . Each experiment set consists of 28 experimental data from 25 RPM to 700 RPM and the relationship between maximum pressure gradient and rotational speed and the maximum Reynolds number Re_max are found. Mass flow rate & maximum Reynolds number Re_max figures can be found. Correlation of friction coefficient f and maximum Reynolds number Re_max have shown in the result experiment data.
