The aim of this research is to find a feasible solution, which may lead to a preliminary conceptual design of a workable Stirling engine. The Stirling engines are frequently called by other names, including hot-air or hot-gas engines, or one of a number of designations reserved for particular engine arrangement. In the beginning of 19th century, due to the rapid development of internal combustion engines and electrical machine, further development of Stirling engines was severely hampered. It is stated that high heat efficiency, low noise operation and ability of Stirling engines to use many fuels meet the demand of the effective use of energy and environmental security. Stirling engine-based units are considered best among the most effective low-power range solar thermal conversion units. In order to analyze and to improve the performance of three main sub-systems of these units, namely the solar receiver, the thermodynamic gas circuit, and the drive mechanism, simulation codes are under development worldwide. It is then concluded, that Stirling engine system is most complicated thermo-mechanical system because of complications in mechanical arrangement caused by phase difference required between compression and expansion spaces and presence of heat exchangers like-heater, cooler, regenerator and auxiliary heat exchangers along with a complicated power control system. ...Download file to see next pagesRead More
