| Summary: | 碩士 === 國立成功大學 === 機械工程學系碩博士班 === 98 === This study present finite time thermodynamic analysis of Stirling heat engine and obtained the maximum power output by using Genetic Algorithm (GA). The thermodynamic models include an endoreversible Stirling engine and an irreversible Stirling engine with imperfect regeneration and heat loss. Each one of those models has two cases which respectively are heat source by convection transfer and by radiation transfer. The relationship between maximum power output and thermal efficiency, moreover, the optimum working temperature of working fluid can be obtained. The case of heat source by convection transfer shows the accuracy of this method by comparing with analytic solution. The second case is about heat source by radiation transfer. We simulated solar driven Stirling engines in the second case and analyzed the effects of various parameters on maximum power output (i.e., times of regeneration process, compression ratio, temperature of heat source…)
In the last case, we have build a model of solar thermal power system, including heat transfer model of collector and endoreversible Stirling engine. The effects of various solar intensity on maximum power output have been discussed.
