Thermodynamic Properties and Equation of State for Tungsten

open access: yesCrystals, 2023
A high-temperature equation of state for tungsten was constructed in this study using experimental data on its thermodynamic properties, thermal expansion, compressibility, and bulk compression modulus. The totality of experimental data were optimized by

Constraining the Inflationary Equation of State

open access: yes, 2011
We explore possible constraints on the inflationary equation state: p=w\rho. While w must be close to -1 for those modes that contribute to the observed power spectrum, for those modes currently out of experimental reach, the constraints on w are much ...

Equation of state of the running vacuum

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Recent studies of quantum field theory in FLRW spacetime suggest that the cause of the speeding up of the universe is the running vacuum (RV), see Moreno-Pulido and Solà Peracaula (Eur Phys J C 82(6):551, 2022; Eur Phys J C 80(8):692, 2020).

Equation of State

open access: yesInverse Heat Conduction and Heat Exchangers, 2020
An equation of state (EOS) is a thermodynamic expression that relates pressure (P), temperature (T), and volume (V). This equation is used to describe the state of reservoir fluids at given conditions.

The State of the Cubic Equations of State

open access: yesIndustrial & Engineering Chemistry Research, 2003
The development of van der Waals cubic equations of state and their application to the correlation and prediction of phase equilibrium properties is presented and analyzed. The discussion starts with a brief account of the contributions to equation of state development during the years before van der Waals.

Cosmological imprint of an energy component with general equation of state [PDF]

open access: yes, 1997
We examine the possibility that a significant component of the energy density of the Universe has an equation of state different from that of matter, radiation, or cosmological constant ({Lambda} ).

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.

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

Non-equilibrium modifications of the nuclear equation of state [PDF]

open access: yes, 1996
Non-equilibrium modifications of the nuclear equation of state are assessed in the framework of Extended Irreversible Thermodynamics. The expected size of the non-equilibrium corrections to quantities like the nuclear-matter incompressibility $K$ and the
