Constant mixing temperature test of a fin-and-tube latent heat thermal energy storage
Scientific Reports, 2022 Thermal energy accumulation is one of the ways how to optimize heat production processes and how to balance the supply and demand of heat in distribution systems. This article presents a design of a fin-and-tube latent heat thermal energy storage (LHTES),

Thermodynamics and Rate Thermodynamics
Journal of Statistical PhysicsApproach of mesoscopic state variables to time independent equilibrium sates (zero law of thermodynamics) gives birth to the classical equilibrium thermodynamics. Approach of fluxes and forces to fixed points (equilibrium fluxes and forces) that drive reduced mesoscopic dynamics gives birth to the rate thermodynamics that is applicable to driven ...

Leidenfrost droplet trampolining
Nature Communications, 2021 The classic Leidenfrost phenomenon is familiar, yet its physics is rather complex. Graeber et al. observe the unexpected development of repeated hopping of a droplet trampolining on its own vapor cushion on a hot plate and show under which conditions ...

The dynamics of thermodynamics
Physica D: Nonlinear Phenomena, 1998 Thermodynamic relations are derived from first principles of mechanics for non-equilibrium processes. Since the key role herein is played by the law of increase of entropy, the latter is analyzed at first. It is shown that its derivation for isolated systems does not allow one to say too much about thermodynamic properties in non-equilibrium conditions.

On phantom thermodynamics [PDF]
Physics Letters B, 2008 The thermodynamic properties of dark energy fluids described by an equation of state parameter $ω=p/ρ$ are rediscussed in the context of FRW type geometries. Contrarily to previous claims, it is argued here that the phantom regime $ω0$ and $S>0$ in the course of the Universe expansion.

Entropy scaling for diffusion coefficients in fluid mixtures
Nature CommunicationsEntropy scaling is a powerful technique that has been used for predicting transport properties of pure components over a wide range of states. However, modeling mixture diffusion coefficients by entropy scaling is an unresolved task. We tackle this issue

Novel post-processing methods for infrared measurements on porous surfaces
Scientific ReportsInfrared (IR) thermography is a key diagnostic tool for non-invasive measurements of surface temperatures. However, for porous materials, particularly those employed in self-pumping transpiration cooling systems, conventional IR techniques suffer from ...
