Abstract :

The purpose of this research was to develop a thermodynamic model for engine via changing the form of regenerator. In conventional beta-type Stirling the working fluid passes between the compression and expansion space via the bypass of the main cylinder. In the present study a new form of regenerator was proposed for the beta-type Stirling engine. In this new form successive homogeneous layers of sguare wire meshes filled the space of displacer piston so that the displacer piston took the role of regenerator and displacer simultaneously. To this end modeling was done using MATLAB software and the obtained results were compared with the published values.
