Roles of bulk viscosity on Rayleigh-Taylor instability: Non-equilibrium thermodynamics due to spatio-temporal pressure fronts

, 2016
Direct numerical simulations of Rayleigh-Taylor instability (RTI) between two air masses with a temperature difference of 70 K is presented using compressible Navier-Stokes formulation in a non-equilibrium thermodynamic framework.

A new perspective on the electron transfer: recovering the Butler-Volmer equation in non-equilibrium thermodynamics.

Physical Chemistry, Chemical Physics - PCCP, 2015
Electron transfer reactions are commonly described by the phenomenological Butler-Volmer equation which has its origin in kinetic theories. The Butler-Volmer equation relates interfacial reaction rates to bulk quantities like the electrostatic potential ...

Non-equilibrium Thermodynamics

2013
In the preceding chapters with few exceptions we studied systems at equilibrium. This means that the systems do not change or evolve over time.

Potential and flux field landscape theory. II. Non-equilibrium thermodynamics of spatially inhomogeneous stochastic dynamical systems.

Journal of Chemical Physics, 2014
We have established a general non-equilibrium thermodynamic formalism consistently applicable to both spatially homogeneous and, more importantly, spatially inhomogeneous systems, governed by the Langevin and Fokker-Planck stochastic dynamics with ...

Non-equilibrium Thermodynamics and Rheology

2001
Local-equilibrium thermodynamics assumes that the equations of state retain the same form out of equilibrium as in equilibrium, but with a local meaning (Prigogine 1961; De Groot and Mazur 1962; Gyarmati 1970). According to this point of view, there is not strictly any especial thermodynamic features characteristic of flowing fluids, since the flow ...

Non-equilibrium Thermodynamics and Physical Kinetics

, 2014
This graduate textbook covers contemporary directions of non-equilibrium statistical mechanics as well as classical methods of kinetics. Starting from phenomenological non-equilibrium thermodynamics, the kinetic equation method discussed and demonstrated

Non-equilibrium thermodynamics and anomalous diffusion

Journal of Physics A: Mathematical and General, 1996
The convenience of a new thermodynamic frame for the description of anomalous diffusion is explored. Our research, which makes use of a recent new definition for entropy arising from multifractal analysis, shows that both dynamical and thermodynamical effects may contribute to non-classical diffusion.

Radiative processes and non-equilibrium thermodynamics

ZAMP Zeitschrift f�r angewandte Mathematik und Physik, 1988
With the assumption of an elementary physical concept meteorologically effective radiative processes (absorption-emission, scattering) can be included consistently in nonequilibrium thermodynamics of irreversible phenomena. Analogously to the usual Gibbs relations a fundamental equation was formulated for monochromatic light rays as the nucleus of the ...

Entropy flux in non-equilibrium thermodynamics

Physica A: Statistical Mechanics and its Applications, 2004
Abstract An important problem in thermodynamics is the link between the entropy flux and the heat flux, for phenomena far from equilibrium. As an illustration we consider here the case of a rigid heat conductor subject to heating. The expression of the entropy flux is determined by the expressions of the evolution equations of the basic variables. It

Non-equilibrium Thermodynamics of Molecular Evolution

Journal of Theoretical Biology, 1998
The evolution of the information complexity of a large database of protein sequences is investigated. The information entropy for protein sequences is determined from their algorithmic complexity and is found to change with evolutionary time at a constant rate.
