本文在Urieli和Berchowitz工作的基础上，采用准定常流动模型对伽马型斯特林发动机进行了热力学分析。对斯特林发动机进行了五个主要领域的分析：压缩室、膨胀室、冷却器、加热器和回热器。导出了有关截面的质量守恒定律和能量方程。一个FORTRAN代码的开发，以解决所有的过程参数，如压力，温度，质量流量，耗散和对流损失的不同的空间（压缩空间，冷却器，回热器，加热器和膨胀空间）作为曲柄角的函数导出的方程。所开发的模型给出了更精确的结果比在文献中的模型的压力分布。
In this study, a thermodynamic analysis of a gamma type Stirling engine is performed by using a quasi steady flow model based on Urieli and Berchowitz's works. The Stirling engine analysis is performed for five principal fields: compression room, expansion room, cooler, heater and regenerator. The conservation law of the mass and the energy equations are derived for the related sections. A FORTRAN code is developed to solve the derived equations for all process parameters like pressure, temperature, mass flow, dissipation and convection losses for the different spaces (compression space, cooler, regenerator, heater and expansion space) as a function of the crank angle. The developed model gave more precise results for the pressure profile than the models available in the literature.
