Abstract
The utilization of waste heat energy has become all attractive attention from the viewpoint of energy security. Many research and development of stirling engine have been carried out as an one of most effective way in recent year. In this study, the development of a thermodynamic model for α type stirling engine which has two control volumes and is considered a heat exchange in the flow passage between both volumes has been down. It has been possible to analyze detail engine performance and heat transfer performance.
