Minimizing entransy dissipation for heat transfer processes with q∝Δ(Tn) and heat leakage

Case Studies in Thermal Engineering, 2022
Heat transfer process with heat leakage and generalized radiative heat transfer law (HTL) [q∝Δ(Tn)] is investigated. Optimality condition for the minimum entransy dissipation (MED) is derived by applying average optimal control theory.
