Equation of State in Relativistic Magnetohydrodynamics: variable versus constant adiabatic index [PDF]

open access: yes, 2007
The role of the equation of state for a perfectly conducting, relativistic magnetized fluid is the main subject of this work. The ideal constant $\Gamma$-law equation of state, commonly adopted in a wide range of astrophysical applications, is compared ...

Prediction Of Solubility Of Solid N-Paraffins In Supercritical Fluids Using Modified Redlich-Kwong Equation Of State

open access: yesReaktor, 2017
Three equation of state are used to predict solubilities of solid n-pafaffins in supercritical fluids. The equations are the Redlich-Kwong, the Soave-Redlich-Kwong, and equation proposed by Hartono et.al. (2003; 2004).

Neutron Star Cooling Within the Equation of State With Induced Surface Tension

open access: yesParticles, 2020
We study the thermal evolution of neutron stars described within the equation of state with induced surface tension (IST) that reproduces properties of normal nuclear matter, fulfills the proton flow constraint, provides a high-quality description of ...

The Polytropic Equation of State of Interstellar Gas Clouds [PDF]

open access: yes, 2000
Models are presented for the polytropic equation of state of self-gravitating, quiescent interstellar gas clouds. A detailed analysis, including chemistry, thermal balance, and radiative transfer, is performed for the physical state of the gas as a ...

Gas–Liquid Flow Behavior in Condensate Gas Wells under Different Development Stages

open access: yesEnergies, 2023
The phase state prediction methods of condensate gas are relatively mature, but the effect of phase changes on gas–liquid mixture flow behavior and the liquid-carrying capacity of gas has not been researched in detail. This study applied PIPESIM software

Equation of State from Lattice QCD Calculations

open access: yes, 2011
We provide a status report on the calculation of the Equation of State (EoS) of QCD at finite temperature using lattice QCD. Most of the discussion will focus on comparison of recent results obtained by the HotQCD and Wuppertal-Budapest (W-B ...

Skyrme models and nuclear matter equation of state [PDF]

open access: yes, 2015
We investigate the role of pressure in a class of generalised Skyrme models. We introduce pressure as the trace of the spatial part of the energy-momentum tensor and show that it obeys the usual thermodynamical relation. Then, we compute analytically the

Analysis of equations of state for polymers

open access: yesPolímeros, 2015
In the literature there are several studies comparing the accuracy of various models in describing the PvT behavior of polymers. However, most of these studies do not provide information about the quality of the estimated parameters or the sensitivity of

Ab Initio Phase Diagram of Chromium to 2.5 TPa

open access: yesApplied Sciences, 2022
Chromium possesses remarkable physical properties such as hardness and corrosion resistance. Chromium is also a very important geophysical material as it is assumed that lighter Cr isotopes were dissolved in the Earth’s molten core during the planet’s ...

History of the Equation of State of Seawater [PDF]

open access: yesOceanography, 2010
As one of few who have been involved in the equation of state of seawater over the last 40 years, the author was invited to review some of the history behind its early development and also the more recent thermodynamic equation of state.
