PERFORMANCE AND ECOLOGICAL OBJECTIVE INVESTIGATION OF TWO-STATE IRREVERSIBLE QUANTUM HEAT ENGINE

Abstract

This paper considers irreversible two-state quantum Carnot heat engine. Basic thermodynamic parameters including power output and energy efficiency are considered, besides ecological function. Ecological function gives someone information about balance between power output and exergy destruction. The results show that ecological function have maximum (optimum) point for a and there is no optimum point for any parameter for x and y. All parameters are compared with each other and the most convenient operation conditions are recommended.
