Discussion on the extensions of the entransy theory

Science China Technological Sciences, 2017
In 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, 2018
Abstract 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 ...

Performance optimization of two-stage latent heat storage unit based on entransy theory

International Journal of Heat and Mass Transfer, 2014
Abstract In order to enhance the performance of the latent heat storage (LHS) process and provide the criterion for the selection and match of the multistage PCMs, the effects of PCMs melting temperatures on the heat storage rate, entransy dissipation rate and heat storage quality were numerically analyzed based on the entransy theory. For the single

A novel method based on entransy theory for setting energy targets of heat exchanger network

Chinese Journal of Chemical Engineering, 2017
Abstract A T-Q diagram based on entransy theory is applied to graphically and quantitatively describe the irreversibility of the heat transfer processes. The hot and cold composite curves can be obtained in the T-Q diagram. The entransy recovery and entransy dissipation that are affected by temperature differences can be obtained through the shaded ...

Analyses of coupled steady heat transfer processes with entropy generation minimization and entransy theory

International Journal of Heat and Mass Transfer, 2018
Abstract The entropy generation minimization and the entransy theory are widely used in the optimization of heat transfer. In this paper, the two theories are applied to coupled steady heat transfer systems. The two different definitions of radiative entransy flux are discussed.
