A performance analysis is performed on the air-standard Diesel cycle using finite-time thermodynamics. The relations between net work and/or power, efficiency, and compression ratio, and the maximum net work and/or power and the corresponding efficiency bound are derived for the cycle with...

The performance of an endoreversible regenerative Brayton heat engine has been studied. The analysis is focused on minimizing irreversibilities associated with the hot and cold heat exchangers and regenerator.

The efficiency bounds at maximum profit are obtained from finite-time exergoeconomic analysis for three common heat transfer laws: Newton's law (n = 1), a linear pheomenological law in irreversible thermodynamics (n = 1), and the radiative heat law (n = 4). The relation between optimal profit...
