本研究主要以可自動啟動之林邦史特靈引擎的設計開發為目標,整合所需之設計概念。另外,本研究利用舒密特模型以及動力方程式來模擬出林邦史特靈引擎(Ringbom Stirling engine)啟動時的移氣器位移、飛輪轉速以及其輸出功率變化。在飛輪轉速方面由於不必使用固定速度假設,飛輪轉速乃由零開始運轉,因此動態模擬更接近實際的情況。本研究可以得出林邦史特靈引擎的PV(壓力-體積)圖,顯示與理想的史特靈循環的不同,並得出活塞位移和移氣器位移之相位差。最後由改變飛輪慣量、熱端溫度、飛輪的曲柄半徑、移氣器的質量以及移氣器中央軸半徑作參數分析,探討相位角對於輸出功率之影響,找出林邦史特靈引擎合適的操作範圍。
This study is aimed at design a automatically-driven Ringbom Stirling.engine.Two types of engines,Type1 and 2, have been developed.Type 2 has been driven automatically.
This study is aimed at numerical simulation Ringbom Stirling engines by combining a thermodynamic and a dynamic models. Numerical predictions of the motion of displacer, angular speed of flywheel, and power output of the engine are carried out. Meanwhile, a parametric study has been performed to evaluate the dependence of engine performance on inertia of the flywheel,temperature in expansion chamber, eccentricity of the flywheel,mass of the displacer,and radius of the central bar of displacer. From the parametric study, the optimal phase angle of displacement is found as a function of the temperature in the expansion chamber,and the operating range of this Ringbom Stirling engine is found.
