摘要: 
本研究主旨在發展一套操作簡單的模擬分析程式,透過數值模擬(MATLAB軟體)計算,針對轉子引擎進行燃燒過程分析,建立轉子引擎熱力過程之相關數學模型,並分階段對數學方程進行簡化,得到壓縮期、燃燒期、膨脹期和換氣期的質量和能量方程式,此外並針對無人飛機(Unmanned Aerial Vehicle)引擎的鰭片進行熱傳分析計算。
從模擬計算中可知轉子引擎燃燒室內氣體壓力以及各區域氣體溫度隨偏心軸轉角而變化,且可由此知各情況下輸出之性能參數。將數值計算和實驗測量結果進行對比分析,可作為設計研發轉子引擎的分析工具。
本文主要將外殼切割為熱區和冷區,其中熱區為燃燒、膨脹、排氣,冷區為進氣、壓縮。模擬顯示,熱區溫度明顯比冷區溫度高約200K。若改變風速和轉速,則風速提高會降低殼溫,而轉速提高會提高殼溫。在實際實驗中轉速會影響風速,但模擬可分開討論。若增加鰭片散熱面積五倍則會降低殼溫100K,若壓縮比從15.67降低至 7.17,則殼溫會降低15K。

In this study, a program based on Matlab was developed to analyze the performance of Unmanned Aerial Vehicle (UAV) rotary engine. Numerical simulation was performed to calculate the combustion process of rotary engine based on the thermodynamic model that has been developed in this study. In the thermodynamic model, the mass and energy conservation equations were used to describe the compression process, the combustion process, the expansion process, and the gas exchange process. Besides, the heat transfer analysis of regarding rotary engine's fin was employed.
In the heat transfer analysis, the housing of rotary was divided into two parts. The hot side includes the wall along which the combustion, the expansion and the exhaust process occur, while the cold side consists of the wall along which the inlet and the compression process occur. The temperature of hot side was higher than the cold side of about 200K. It was found that increasing the wind velocity would decrease the housing temperature, and rising engine speed would increase the housing temperature. However, in actual operation the cooling velocity is determined by the aviation speed which is in turn affected by the engine speed.
Besides, results of calculations showed that increasing the fin area of rotary engine by a factor of 5 would decrease the housing temperature for 100K. If the compression ratio is reduced from 15.0 to 7.17, the maximum wall temperature would decrease 15K.
