Abstract
This paper aims to study the effect of mechanism and geometrical parameters on the shaft work of alpha-type Stirling engine with V-cylinder arrangement and find the appropriate value of geometrical parameters to get the maximum value of shaft work output. The equation of motions of both expansion and compression pistons and the variations of volumes and pressures inside the cylinders are expressed in dimensionless forms. Schmidt analysis and Senft’s shaft work theory are used to build dimensionless thermodynamic models in order to derive dimensionless shaft work and optimal geometrical parameters for achieving the maximum efficiency
Highlights
Stirling engine is a heat engine that works as a cycle of expansion and compression of air or other working gas by the effects of temperature differences
Batmaz I, Ustun S [2] employed double heaters for solar power heating V-type Stirling engine which the unpressurized engine gave the best performance at 950 °C heater surface
The optimization of the alpha Stirling engine were proposed by Homutescu and Balanescu [4]
Summary
Stirling engine is a heat engine that works as a cycle of expansion and compression of air or other working gas by the effects of temperature differences. From these processes, the conversion of energy from heat to mechanical energy in addition, the Stirling engine is a closed-loop cycle engine that has a constant working gas is sealed without transferring to the environment. [1] built and tested performance of the alpha Stirling engine. Batmaz I, Ustun S [2] employed double heaters for solar power heating V-type Stirling engine which the unpressurized engine gave the best performance at 950 °C heater surface. Scollo et al [5]
