| Abstract: | The finite time exergoeconomic optimal performance of an universal endoreversible heat engine cycle model consisting of two adiabatic branches, two heating branches and one cooling branches has been analyzed and optimized using finite time thermodynamics. The analytical formulae of the profit rate and the thermal efficiency of the endoreversible heat engine cycle were derived. The comparative performance analyses for the cycles were carried out by detailed numerical examples. The results obtained herein include the performance characteristics of Carnot, Diesel, Otto, Atkinson, Brayton and Dual cycles. |
| Keywords: | finite time thermodynamics endoreversible heat engine cycle exergoeconomic performance |
