Entransy is a parameter proposed in recent years to describe the potential of heat in an object. Its balance equation was established based on the energy equation of heat transfer, which contains entransy, entransy flow, entransy dissipation and entr

Constructal theory has been extensively used to analyze and optimize many different shapes and structures in both living and non-living systems. It is generally considered to be a law that could govern the evolutions of shapes and structures in biolo

Recently, the analogy between the processes of heating a solid body and charging an electric capacitor was deemed as “heat-work analogy” and argued that it was false and violated the second law of thermodynamics. It was claimed that the two proce
