| Abstract: | An irreversible solar-driven Stirling heat engine system is established,in which not only radiation-convection heat losses from the solar collector to the ambient but also the regeneration loss and other irreversibilities of the heat engine are taken into account.Based on thermodynamic analysis method and the optimal control theory,the optimum relationship between the overall efficiency of the system and the operating temperature of the collector are derived and the related performance bounds and optimal va... |
