Thermal performance in heat exchangers by the irreversibility, effectiveness, and efficiency concepts using nanofluids [PDF]

open access: yesЖурнал інженерних наук, 2020
The objective of the work is to obtain the outlet temperatures of the fluids in a shell and tube heat exchanger. The second law of thermodynamics is applied through the concepts of efficiency, effectiveness, and irreversibility to analyze the results ...

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.

Thermodynamical properties of the Universe with dark energy [PDF]

open access: yes, 2006
We have investigated the thermodynamical properties of the Universe with dark energy. Adopting the usual assumption in deriving the constant co-moving entropy density that the physical volume and the temperature are independent, we observed some strange ...

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.

Thermodynamics and Chemistry of the Early Universe [PDF]

open access: yes, 2018
The interplay between chemistry and thermodynamics determines the final outcome of the process of gravitational collapse and sets the conditions for the formation of the first cosmological objects, including primordial supermassive black holes.

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.

Confinement and the AdS/CFT Correspondence [PDF]

open access: yes, 2000
We study the thermodynamics of the confined and unconfined phases of superconformal Yang-Mills in finite volume and at large N using the AdS/CFT correspondence.
