The Application of Entransy Dissipation Theory in Optimization Design of Heat Exchanger
The heat conduction and fluid friction are two main detrimental irreversibilities in heat exchanger. According to the entransy dissipation theory, the entransy dissipation can be employed to quantify these two irreversibilities. In the present work, the optimization of heat exchanger design is investigated by applying the entransy dissipation theory ...

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

Entransy - a Novel Theory in Heat Transfer Analysis and Optimization [PDF]
It has been estimated that, of all the worldwide energy utilization, more than 80% involves the heat transfer process, and the thermal engineering has for a long time recognized the huge potential for conserving energy and decreasing CO2 release so as to reduce the global warming effect through heat transfer efficiency techniques (Bergles, 1988, 1997 ...
