Thermodynamics of the viscous fluid from an observer's viewpoint

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
The development of the non-equilibrium thermodynamics of the viscous fluid not using the local thermodynamic equilibrium hypothesis is considered. The theory is based on the causal mechanics of the heat conducting continuum, which includes the 1st law of

Braun-Le Chatelier principle in dissipative thermodynamics

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
Braun-Le Chatelier principle is a fundamental result of equilibrium thermodynamics, showing how stable equilibrium states shift when external conditions are varied. The principle follows from convexity of a thermodynamic potential.

Thermodynamics of Various Entropies in Specific Modified Gravity with Particle Creation

Advances in High Energy Physics, 2018
We consider the particle creation scenario in the dynamical Chern-Simons modified gravity in the presence of perfect fluid equation of state p=(γ-1)ρ. By assuming various modified entropies (Bekenstein entropy logarithmic entropy, power law correction ...

The Second Law Today: Using Maximum-Minimum Entropy Generation

Entropy, 2015
There are a great number of thermodynamic schools, independent of each other, and without a powerful general approach, but with a split on non-equilibrium thermodynamics. In 1912, in relation to the stationary non-equilibrium states, Ehrenfest introduced

Can Quantum Correlations Lead to Violation of the Second Law of Thermodynamics?

Entropy, 2021
Quantum entanglement can cause the efficiency of a heat engine to be greater than the efficiency of the Carnot cycle. However, this does not mean a violation of the second law of thermodynamics, since there is no local equilibrium for pure quantum states,

Making Sense of Gravitational Thermodynamics

Philosophy of Physics
The use of statistical methods to model gravitational systems is crucial to physics practice, but yet the extent to which thermodynamics and statistical mechanics genuinely apply to these systems is a contentious issue.

Fractal C60 fullerene aggregation: Equilibrium thermodynamics approach [PDF]

, 2020
Using dynamic light scattering (DLS) data we showed that the main physico-chemical parameters characterizing C60 fullerene aggregation in solution, viz. equilibrium aggregation constant and fractal number, may be obtained from equilibrium thermodynamics ...

Entropy Principle and Recent Results in Non-Equilibrium Theories

Entropy, 2014
We present the state of the art on the modern mathematical methods of exploiting the entropy principle in thermomechanics of continuous media. A survey of recent results and conceptual discussions of this topic in some well-known non-equilibrium theories

Physicochemical Mechanics and Nonequilibrium Chemical Thermodynamics

, 2023
Equilibrium thermodynamics answers the question, “by how much?” Nonequilibrium thermodynamics answers the question “how fast?” The physicochemical mechanics approach presented in this article answers both of these questions.
