Discussion on the extensions of the entransy theory
Science China Technological Sciences, 2017In this paper, the preconditions for the extensions of the entransy theory are summarized and discussed. As the physical meaning of entransy is the “potential energy” of thermal energy, the concepts and analyses method of the entransy theory can be extended based on the viewpoint of potential energy.

Design of heat exchanger network based on entransy theory
Chinese Journal of Chemical Engineering, 2018Abstract The heat exchanger network (HEN) synthesis problem based on entransy theory is analyzed. According to the characteristics of entransy representation of thermal potential energy, the entransy dissipation represents the irreversibility of the heat transfer process, the temperature difference determines the entransy dissipation, and four HEN ...

Application of entransy dissipation theory in heat convection
Frontiers of Energy and Power Engineering in China, 2009In the present work, formulas for calculating the rates of the local thermodynamic entransy dissipation in convective heat transfer in general, and the internal and external flows in particular, are established. Practically, these results may facilitate the application of entransy dissipation theory in thermal engineering. Theoretically they shed light

Optimization of fin geometry in heat convection with entransy theory
Chinese Physics B, 2013The entransy theory developed in recent years is used to optimize the aspect ratio of a plate fin in heat convection. Based on a two-dimensional model, the theoretical analysis shows that the minimum thermal resistance defined with the concept of entransy dissipation corresponds to the maximum heat transfer rate when the temperature of the heating ...
