Isothermal thermodynamic analysis investigation of the Stirling engine types (alpha, beta, gamma): A theatrical study

Abstract

Stirling engine is type of external combustion engines, closed and cyclic that operates on the Stirling cycle. This paper presents a theatrical thermodynamic investigation to compare between Stirling engine major types (alpha, beta, gamma) with ideal isothermal model based on Schmidt analysis, air as the working fluid was tested. The impact of hot source temperature and cold sink temperature, engine speed and mass of working fluid were also considered. The results shows that gamma engine is more efficient than other types with output power 197.8 W while beta with 195 W and alpha with 140 W based on modeling data in this study.
