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 rotating speed, tube or wire diameter of heat exchangers, the free-flow area of heat exchangers or 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 optimum conditions have been derived as shown in table 1. Existing engines do not meet the condition very well, especially for ratio of free flow areas.
