Abstract
Stirling engines are external combustion heat engines. This condition extends the list of energy sources thatcan be used. Although this thermal engine precedes the internal combustion engines, had its development suppresseddue to technical problems of operation and influence of the petroleum industry. However, the research and developmentof Stirling engines has gained momentum in the last decade in view of a possible shortage of fossil fuels as well as thevast amount of fuels that can provide thermal energy to Stirling engines such as biomass, solar, natural gas, petroleumproducts, among others. The purpose of this study is to develop the simulation for alpha-type Stirling engine comparingthe Schmidt analysis based on the isothermal expansion and compression of an ideal gas and an adiabatic system. Para-metric study is used to investigate the effect of operation and geometric parameters on the engine performance. The effectof the dead volume ratio, operating temperature, swept volume ratio and phase angle.
