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 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 ...

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 ...

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 ...

Compact Stars in the vBag Model and Its f-Mode Oscillations

open access: yesUniverse, 2023
Electromagnetic (EM) observations and gravitational wave (GW) measurements enable us to determine the mass and radius of neutron stars (NSs) and their tidal deformability, respectively.

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 ...

Chiral dynamics of the nuclear equation of state [PDF]

open access: yes, 1998
We present a new chiral power expansion scheme for the nuclear equation of state. The scheme is effective in the sense that it is constructed to work around nuclear saturation density.

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

ab Initio DFT and MD Simulations Serving as an Anchor for Correcting Melting Curves Reported by DAC and SW Experiments—Some Transition Metals as Illustrative Examples

open access: yesCrystals, 2023
The pressure–temperature scales in DAC and shock wave (SW) experiments should be corrected by taking into account the thermal pressure shifts. In the present contribution, it is further claimed that first-principle ab initio DFT and MD simulations should
