International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023 The current investigation analyses the convective heat transfer performance, entropy generation, and entransy evaluation of swirl flows generated by distorted radial fins (DRF). As swirl flows and various vortical structures induce large temperature gradients, second law and entransy analyses are necessary to thoroughly evaluate their true ...

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.
