| Abstract: | A potential application of closed-cycle Brayton plants for aerospace electrical power system is presented. The performance optimization of a simple irreversible closed-cycle Brayton plant is studied by using finite-time thermodynamic methods in this paper. The optimal relation between power output and efficiency of the irreversible cycle is derived. The results are more significant than those by classical thermodynamic methods. |
