Thermodynamic volume of cosmological solitons

open access: yesPhysics Letters B, 2017
We present explicit expressions of the thermodynamic volume inside and outside the cosmological horizon of Eguchi-Hanson solitons in general odd dimensions. These quantities are calculable and well-defined regardless of whether or not the regularity condition for the soliton is imposed.

Thermodynamics of 5D charged rotating black holes: a counterterms treatment

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We use the counterterms subtraction method to calculate various thermodynamical quantities for charged rotating black holes in five-dimensional minimal gauged supergravity (Chong et al.

Impact of thermodynamic hypotheses on the calculation of the quantity of CO2 stored in a saline aquifer [PDF]

open access: yesMATEC Web of Conferences, 2023
The aim of this paper is to study the impact of thermodynamics models on the CO2 storage capacity of an aquifer, by using modelling and simulation of transport phenomena in porous media.

Application of the Molecular Interaction Volume Model for Calculating Activities of Elements in Ferromanganese Alloys: Mn-C, Mn-Fe, Fe-C, and Mn-Fe-C Systems

open access: yesCrystals, 2022
The molecular interaction volume model (MIVM) developed by Tao is a fluid-based model derived from statistical thermodynamics and fluid phase equilibria.

Thermodynamics and weak cosmic censorship conjecture in extended phase spaces of anti-de Sitter black holes with particles’ absorption

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The thermodynamics and weak cosmic censorship conjecture in extended phase spaces of charged anti-de Sitter black holes describing the massive gravity are investigated by the absorptions of the scalar particle and fermion.

Discretization of continuum physics – a comparison of numerical methods from a physical point of view; pp. 145–154 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2008
For numerical calculations in continuum physics partial differential equations and the space-time are discretized. This can be done in different ways. Common approaches are finite difference methods and finite element methods, more rarely finite volume ...

A New Entropy Function to Analyze Isentropic Processes of Ideal Gases with Variable Specific Heats

open access: yesEntropy, 2022
A new entropy function s+ is defined in terms of the existing entropy function s° and temperature as s+ = s° − R lnT to facilitate the analysis of isentropic processes of ideal gases with variable specific heats. The function s+ also makes it possible to

Defining the pressures of a fluid in a nanoporous, heterogeneous medium

open access: yesFrontiers in Physics, 2022
We describe the thermodynamic state of a single-phase fluid confined to a porous medium with Hill’s thermodynamics of small systems, also known as nanothermodynamics.
