Review of Jones-Wilkins-Lee equation of state

open access: yesEPJ Web of Conferences, 2011
The JWL EOS is widely used in different forms (two, three terms) according to the level of accuracy in the pressure-volume domain that applications need.

An equation of state for purely kinetic k-essence inspired by cosmic topological defects

open access: yes, 2016
We investigate the physical properties of a purely kinetic k-essence model with an equation of state motivated in superconducting membranes. We compute the equation of state parameter $w$ and discuss its physical evolution via a nonlinear equation of ...

Equation of state for systems with Goldstone bosons

open access: yes, 2002
We discuss some recent determinations of the equation of state for the XY and the Heisenberg universality class.Comment: 5 pages, Proceedings of the Conference "Horizons in Complex Systems", Messina; in honor of the 60th birthday of H.E ...

Nonparametric Reconstruction of the Dark Energy Equation of State

open access: yes, 2010
A basic aim of ongoing and upcoming cosmological surveys is to unravel the mystery of dark energy. In the absence of a compelling theory to test, a natural approach is to better characterize the properties of dark energy in search of clues that can lead ...

Investigation of methane/drilling mud phase behavior and its influence to hydrocarbon drilling activity

open access: yesEnergy Science & Engineering, 2019
Knowledge of methane dissolution behavior in drilling mud is of major importance to early kick detection and well control operation in oil and gas drilling industry.

The Evolution of Parallel Electron Temperature in Magnetospheric Reconnection Inflows

open access: yesGeophysical Research Letters
Using data from NASA's Magnetospheric Multiscale mission captured in a reconnection inflow on the magnetospheric side of Earth's dayside magnetopause, we find a region where the heat flux density gradient term balances the parallel compression term in ...

Zero-Temperature Equation of State of a Two-Dimensional Bosonic Quantum Fluid with Finite-Range Interaction

open access: yesCondensed Matter, 2019
We derive the two-dimensional equation of state for a bosonic system of ultracold atoms interacting with a finite-range effective interaction. Within a functional integration approach, we employ a hydrodynamic parameterization of the bosonic field to ...

Cohesive Energy Densities Versus Internal Pressures of Near and Supercritical Fluids

open access: yesMolecules, 2019
Over half a century ago, Wiehe and Bagley suggested that a product of the internal pressure and molar volume of a liquid measures the energy of nonspecific intermolecular interactions whereas the cohesive energy reflects the total energy of ...

N_f=2+1 flavour equation of state

open access: yes, 2010
We conclude our investigation on the QCD equation of state (EoS) with 2+1 staggered flavors and one-link stout improvement. We extend our previous study [JHEP 0601:089 (2006)] by choosing even finer lattices. These new results [for details see arXiv:1007.

Thermodynamic Property Model of Wide-Fluid Phase Propane [PDF]

open access: yesITB Journal of Engineering Science, 2007
A new thermodynamic property model for propane is expressed in form of the Helmholtz free energy function. It consists of eight terms of the ideal-gas part and eighteen terms of the residual part.
