Abstract:	本研究透過數值分析之方式，模擬以理想氣體為工作流體之gamma型態史特靈引擎內部震盪流場與整體溫度分布情形，係利用計算流體動力學分析軟體ESI-CFD來執行運算；於本研究中，將以2-D之數學模型進行整體gamma型態史特靈引擎結構之建模計算，並針對單、雙動力汽缸做比較。時間與體積之變化將表現出對應之暫態的壓力變化及溫度場之分布；模擬之溫度場變化與實際實驗結果呈現出相當好的比對。最後，利用porous-media模組進行初步之復熱再生器的模擬研究。 This research study a numerical analysis on the oscillatory flow and temperature distribution inside a gamma type Stirling engine with ideal gas as working fluid. The CFD code used in the investigation for modeling is ESI-CFD. In this study, a 2-D mathematical model is formulated for a full scale gamma-configuration Stirling engine with single and dual power pistons. Variation of time, piston volume with pressure and temperature are presented. The calculated temperature distribution results compare well with experimental results from the other research in our group. Also, a preliminary study for an initial thermal equilibrium porous-media model used in CFD codes for simulation of Stirling regenerators is presented.
