Effect of the heat transfer law on the finite-time, exergoeconomic performance of heat engines

The efficiency bounds at maximum profit are obtained from finite-time exergoeconomic analysis for three common heat transfer laws: Newtonʹs law (n = 1), a linear pheomenological law in irreversible thermodynamics (n = 1), and the radiative heat law (n = 4). The relation between optimal profit and efficiency of an endoreversible Carnot engine is derived on the basis of the general heat-transfer law q∝Δ(Tn).
