Abstract :

The purpose of this article is to develop a thermodynamic model appropriate to be piston Stirling engine beta-type deformation is to increase efficiency and output power l. For this purpose, thermodynamic modeling is done in two parts, the first part was isothermal modeling and then using the results of numerical modeling to model the geometry of adiabatic method is performed. In fact, the results of the first part (modeling isothermal), as initial values of the second part (modeling adiabatic), is used. Modeling was performed using MATLAB software and by changing the diameter of the piston, the heat input, heat output and engine efficiency. The results obtained were compared with published values, compared.
