A multistage irreversible Carnot heat engine system operating between a finite thermal capacity high-temperature fluid reservoir and an infinite thermal capacity low-temperature environment with generalized convective heat transfer law [q∝(ΔT)m] and the irreversibility of heat resistance and...

An optimal performance analysis of an internally and externally irreversible solar driven heat engine has been carried out. A Carnot-type heat engine model for radiative and convective boundary conditions was used to consider the effects of the finite-rate heat transfer and internal...

We treat an irreversible extension of the Carnot problem of maximum mechanical work delivered from a system of a finite-resource fluid and a bath fluid. For a derived work functional, Pontryagin's maximum principle is applied to determine optimal states and optimal controls. These are...
