Exergeo-economic performance bound and optimisation criteria for heat engines

SYNOPSIS Finite-time thermodynamics and exergeoeconomics are combined to form a new analysis method called finite-time exergeoeconomics in this paper. The optimal thermal efficiency and profit rate holographic spectrum for the heat engine is derived. The derivation is used to obtain the efficiency bound at maximum profit rate and the optimisation criteria for selecting thermodynamic parameters of the heat engine cycles. The results provide a solid theoretical basis for design and evaluation of practice heat engines.
