【摘要】：斯特林发动机是一种能以多种燃料为能源的闭循环回热式发动机。本文研究一种β型斯特林发动机的动力学与热力学耦合分析模型。该耦合模型中考虑发动机的热损失以及不可逆性,以期能够得到更加接近实际工况的数据。通过数值模拟,分析回热器性能以及无益容积对发动机性能的影响。另外,研究得到不同几何参数下的发动机净输出功以及热效率,并评估传动机构、无益容积比以及回热器性能对发动机最大输出净功的影响。结果表明,发动机效率随着无益容积的增大而降低,随着回热器性能的降低而降低。
[Abstract]:Sterling engine is a closed cycle reheat engine which can use a variety of fuels as energy. In this paper, a coupling analysis model of dynamics and thermodynamics for 尾-type Sterling engine is studied. In this coupling model, the heat loss and irreversibility of the engine are considered in order to obtain the data which are more close to the actual working conditions. Through numerical simulation, the influence of regenerator performance and unbeneficial volume on engine performance is analyzed. In addition, the net output power and thermal efficiency of the engine under different geometric parameters are studied, and the effects of transmission mechanism, unbeneficial volume ratio and regenerator performance on the maximum output net work of the engine are evaluated. The results show that the engine efficiency decreases with the increase of useless volume and decreases with the decrease of regenerator performance.
