Ecological performance of an endoreversible Carnot heat engine with complex heat transfer law

Abstract

The optimal ecological performance of an endoreversible Carnot engine, in which the transfer between the working fluid and the heat reservoirs obeys a complex heat transfer law, including generalized convective heat transfer law and generalized radiative heat transfer law, Q∝ (Δ T n ) m , is derived by taking into account an ecological optimization criterion as the objective function, which consists of maximizing a function representing the best compromise between the power output and entropy generation rate of the heat engine. The obtained results include the optimal ecological performance of the endoreversible Carnot heat engine with various heat transfer laws obtained in many studies.
