OPTIMIZATION OF A γ-TYPE STIRLING ENGINE PERFORMANCE BASED ON AN EXPERIMENTAL APPROACH

Adrian Ioan BOTEAN

Abstract


Using a γ-type Stirling engine, with a total cylinder capacity of 20 cm3, this paper aims to establish the indicated power Pi and the thermal efficiency η according to the temperature gradient between its component parts (expansion cylinder, radiator and power cylinder). This temperature gradient is controlled by thermal barriers (klingerit gaskets) mounted in four variants for the study.


Key words: gamma Stirling engine, gradient temperature, working fluid, power, speed, thermodynamic cycle, kling erit gaskets, thermal efficiency
