摘要:Irreversibility (that is, the “one-sidedness” of time) of a physical process can be characterized by using Lyapunov functions in the modern theory of stability. In this theoretical framework, entropy and its production rate have been generally regarded as Lyapunov functions ...

摘要:Abstract(#br)The demand for more efficient energy utilization is leading to the need for efficient thermal energy storage (TES) systems. High temperature, low thermal conductivity concrete has been widely used in solid TES modules. The thermal conduction in concrete is improved b...

摘要:Abstract(#br)Ballistic-diffusive heat conduction in multiply-constrained nanostructures is theoretically studied based on the phonon Boltzmann transport equation. The results show that different constraints influence the thermal transport in different ways. In the direction paral...

摘要:Abstract(#br)The least action principle is used in various disciplines including linear transport processes. However, non-equilibrium thermodynamic analyses of linear transport processes involve the dot product of the thermodynamic flux and the thermodynamic force which must...

摘要:Abstract(#br)The existing phonon Monte Carlo (MC) for ballistic-diffusive heat conduction are limited to small and simple structures owing to the huge time cost following with the increasing scale. This article presents a new hybrid phonon Monte Carlo-diffusion method for ballist...

摘要:Abstract(#br)The optimization principle, Δ T/T = const, was wrongly shown to hold for balanced counter-flow heat exchangers due to an inappropriate analogy between a balanced counter-flow heat exchanger and a one-dimensional thermal insulation system in a paper entitled “A g...
