This study strives to provide a clear explanation of the Stirling engine and its efficiency using new automation technology Lab View software. heat was invented by Stirling, Scottish in 1918. The engine’s working principles are based on laws thermodynamics ability volume expansion ideal gases at different temperatures. Basically there three types engines: gamma, beta alpha models. focuses type ...

Recent progress on a Stirling engine driven hea t pump is described and a modeling technique for predicting engine dynamics is developed. The system described represents a very p romising configuration of engine driven heat pump, because o f the long life characteristics of the free-piston Stirling engin e and the hermetic nature of both the engine and refrigerant work ing fluids. Recent change...

Energy and exergy analyses were carried out for a pilot parabolic solar dish-Stirling System. The system was set up at a site at Kerman City, located in a sunny desert area of Iran. Variations in energy and exergy efficiency were considered during the daytime hours of the average day of each month in a year. A maximum collector energy efficiency and total energy efficiency of 54% and 12.2%, res...

The free-piston Resonance Stirling engine forms a new “ electricity producing heating system ”. Its compact assembly operates reliably and at high efficiency, setting standards for small systems. Complete units are currently submitted to prolonged test program, preparing their production an industrial scale. engines heated from outside by FLOX-burner (flameless flue gas recirculation burner), e...

In this paper, a comparison of exergetic models between two hot air engines (a Gamma type Stirling prototype having a maximum output mechanical power of 500 W and an Ericsson hot air engine with a maximum power of 300 W) is made. Referring to previous energetic analyses, exergetic models are set up in order to quantify the exergy destruction and efficiencies in each type of engine. The repartit...
