On Thermodynamically Compatible Finite Volume Schemes for Continuum Mechanics

SIAM Journal on Scientific Computing, 2022
In this paper we present a new family of semi-discrete and fully-discrete finite volume schemes for overdetermined, hyperbolic and thermodynamically compatible PDE systems. In the following we will denote these methods as HTC schemes. In particular, we consider the Euler equations of compressible gasdynamics, as well as the more complex Godunov-Peshkov-

Effect of pore structure on capillary condensation in a porous medium [PDF]

, 2009
The Kelvin equation relates the equilibrium vapor pressure of a fluid to the curvature of the fluid-vapor interface and predicts that vapor condensation will occur in pores or irregularities that are sufficiently small.

Equation of state for agents on graphs

, 2005
Choice models for populations of agents on graphs are studied in terms of statistical thermodynamics. Equations of state are derived and discussed for different connectivity schemes, utility approximations, and temperature and volume regimes.

Incremental least action principle in the framework of thermodynamics of irreversible processes

Physical Review Research, 2020
In this paper, an incremental least action principle is proposed using the framework of the thermodynamics of irreversible processes. First, we establish that an extensive thermodynamic potential defined over an infinitesimal volume satisfies a ...

Locally Anisotropic Kinetic Processes and Thermodynamics in Curved Spaces [PDF]

, 2000
The kinetic theory is formulated with respect to anholonomic frames of reference on curved spacetimes. By using the concept of nonlinear connection we develop an approach to modelling locally anisotropic kinetic processes and, in corresponding limits ...

Stochastic and Macroscopic Thermodynamics of Strongly Coupled Systems

Physical Review X, 2017
We develop a thermodynamic framework that describes a classical system of interest S that is strongly coupled to its thermal environment E. Within this framework, seven key thermodynamic quantities—internal energy, entropy, volume, enthalpy, Gibbs free ...

Reentrant Phase Transitions in Rotating AdS Black Holes [PDF]

, 2013
We study the thermodynamics of higher-dimensional singly spinning asymptotically AdS black holes in the canonical (fixed J) ensemble of extended phase space, where the cosmological constant is treated as pressure and the corresponding conjugate quantity ...

Energy-conserving physics for nonhydrostatic dynamics in mass coordinate models [PDF]

Geoscientific Model Development
Motivated by reducing errors in the energy budget related to enthalpy fluxes within the Energy Exascale Earth System Model (E3SM), we study several physics–dynamics coupling approaches.
