PERFORMANCE AND ECOLOGICAL OBJECTIVE INVESTIGATION OF TWOSTATE IRREVERSIBLE QUANTUM HEAT ENGINE

Abstract

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