This study deals with the thermodynamic design of Stirling engine. Eleven design parameters are optimized. The optimum conditions are determined, first. Most of those are that x∂W_<net>/∂x=ξW_<net>, where W_<net> is the net power and x an optimizing design parameter, under the condition as rotating speed is optimized to make the net power takes the maximum, and ξ is selected 0,±0.1 or 0.9. To optimize porosity and regenerator volume, the efficiency (net output work/heat input) is maximized. It is confirmed that the all eleven parameters can be optimized based on the conditions. The effects of working gas average pressure and the temperature ratio of heat source to heat sink are examined. Because a wrong equation is used to evaluate pressure loss in the regenerator, only qualitative discussion is available on the results.
