Mesoscopic virial equation for nonequilibrium statistical mechanics [PDF]

open access: yesNew Journal of Physics, 2016
We derive a class of mesoscopic virial equations governing energy partition between conjugate position and momentum variables of individual degrees of freedom.

Short distance modification of the quantum virial theorem

open access: yesPhysics Letters B, 2017
In this letter, we will analyse the deformation of a semi-classical gravitational system from minimal measurable length scale. In the semi-classical approximation, the gravitational field will be analysed as a classical field, and the matter fields will ...

Virial expansions and augmented van der Waals approach: Application to Lennard-Jones-like Yukawa fluid [PDF]

open access: yesCondensed Matter Physics, 2015
We argue that recently proposed [Melnyk et al., Fluid Phase Equilibr., 2009, 279, 1] a criterion to split the pair interaction potential into two parts, one of which is forced to be responsible for excluded volume in the system, results in the ...

VIRIAL EXPANSION OF THE NUCLEAR EQUATION OF STATE [PDF]

open access: yesInternational Journal of Modern Physics E, 2012
We study the equation of state (EOS) of nuclear matter as function of density. We expand the energy per particle (E/A) of symmetric infinite nuclear matter in powers of the density to take into account 2, 3, …, N-body forces. New EOS are proposed by fitting ground state properties of nuclear matter (binding energy, compressibility and pressure) and ...

QCD equation of state in a virial expansion [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2009
We describe recent three-flavor QCD lattice data for the pressure, speed of soun d and interaction measure at nonzero temperature and vanishing chemical potentia l within a virial expansion. For the deconfined phase we use a phenomenological model which includes non-pert urbative effects from dimension two gluon condensates that reproduce the free en ...

Calculation of the Virial and Fugacity Coefficients of Heavy Water Using New Generalized Equation of State [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2022
By replacing hydrogen with deuterium in water molecules, the energy level of molecular bonds changes which cause different physical, chemical, nuclear, and biological properties.

Modeling of Some Thermodynamic Properties of UF6 at Low Pressure Using Correlation Function [PDF]

open access: yesJournal of Nuclear Research and Applications, 2021
The properties of uranium hexafluoride (UF6) are of importance to the nuclear industry as a precursor for the enrichment. Therefore it is of importance to obtain the most accurate properties for such a strategic compound.

Gaseous density calculation by means of relative permittivity measurement

open access: yesMeasurement: Sensors, 2021
This study presents a gaseous density calculation method on the basis of relative permittivity measurement. The relative permittivity of a gas sample is measured by using a cylindrical microwave cavity resonator in wide temperature and pressure ranges ...

A new simplified virial equation of state for high temperature and high pressure gas

open access: yesAIP Advances, 2022
In this paper, in order to accurately describe the high temperature and high pressure state of gas under detonation conditions, a new simplified form of the virial equation of state (EOS)—the Virial–Peng–Long (VPL) EOS—is proposed based on the ...

Analysis of p, T, ρ-data for all fluid states via comparison with a transcribed Van der Waals equation

open access: yesChemical Thermodynamics and Thermal Analysis, 2021
The old concepts of the Van der Waals equation (vdW EOS) and of the virial equation, truncated to the second virial coefficient, can be rewritten with a function defined as cc=(p−R·T/M)/ρ2. This function arises from introducing the ideal gas law into the
