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.

Geometry Optimization of Self‐Similar Transport Network
Mathematical Problems in Engineering, Volume 2011, Issue 1, 2011., 2011 We optimize geometries of various self‐similar transport networks using a three‐step strategy based on the entransy theory. Using this optimization method, we obtained optimal relationships of geometric parameters of T‐shape networks for fluid flow, heat conduction, convective heat transfer, and other transport phenomena.

Constructal optimization for an organic fluid shell-and-tube heat exchanger based on entransy theory [PDF]
SCIENTIA SINICA Technologica, 2020 Based on constructal theory and entransy theory, constructal optimization of a shell-and-tube heat exchanger (STHE) for the organic fluid evaporation process is performed using a complex function as an optimization objective. The complex function is composed of the entransy dissipation rate (EDR) caused by heat transfer and the total pumping power. The

Discussion on the application of entransy theory to heat-work conversion processes
Acta Physica Sinica, 2014 Applications and limitations of the entransy theory for heat-work conversion processes are analyzed and discussed in this paper. Our analyses for the Carnot cycle show that the system entransy of the Carnot cycle is in balance, but the relationship, dG=T2dS, does not exsit between the concepts of entransy and entropy.
