Optimization of Design Parameters of Stirling Engine

Abstract

This study deals with the thermodynamic design of Stirling engine. It is selected as the optimum condition that the net output power of the engine takes the maximum with respect to the variation of parameters, such as phase angle, the amount of heat storage material, rotating speed, tube or wire diameter of heat exchangers, the free-flow area of heat exchangers of the volume of heat exchangers. The net output is calculated from indicated power of multi-element simulation in which flow resistance is neglected, subtracting friction power loss calculated from existing correlations. The comparison with an existing engine has revealed that it is possible to improve engines, especially on the amount of heat storage material.
