Optimization of geometrical parameter for V-type alpha Stirling engine based on dimensionless analysis

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 efficienc

Investigation on Stability and Performance of a Free-piston Stirling Engine

AbstractThe stable operation of a free-piston Stirling engine will be achieved when both engine configurations and operating conditions are optimum. This paper presents stability and performance investigation of free-piston Stirling engine. Isothermal analysis is considered in the simulation. Dynamic motion of engine pistons such as the displacer and the power piston are both obtained. For engine design, the optimum parameters are given such as engine specifications, engine characteristics and working conditions to yield the maximum efficiency and reliability. The prototype was built and tested. The comparison of both experimental and simulation results are provided and discussed
