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 ...

A New Fourth Order Compression Dependent Equation of State

open access: yesEast European Journal of Physics
This study introduces a new first- to fourth-order exponential equation of state (EOS) to enhance accuracy across varying compression levels. The proposed exponential EOS is compared to the widely used fourth-order Birch-Murnaghan EOS, and it not only ...

Calculation of Thermodynamic properties of Fluid Using a New Equation of State [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1992
Using the Lennard-Jones (12-6) potential, a new equation of state is obtained that can predict properties of both gases and liquids relatively well. This equation of state is given as (Z-a)V2=(A/V2)-B, where Z is the compressibility factor, A and B are ...

CURVES OF THERMODYNAMIC STATES IN SOME FLUIDS WITH DISPERSION

open access: yesTASK Quarterly, 2017
Variations in the thermodynamic state of a dispersive medium, caused by sound, are studied. A bubbly liquid and a Maxwell fluid are considered as examples. Curves in the plane of thermodynamic states are plotted.

Assessing Density-Functional Theory for Equation-Of-State

open access: yesComputation, 2018
The last decade has seen a continued development of better experimental techniques to measure equation-of-state (EOS) for various materials. These improvements of both static and shock-compression approaches have increased the accuracy of the EOS and ...

Equation of State of the Hard-Sphere Crystal

open access: yes, 1996
A new approach to the averaged two-particle distribution function of a crystalline phase is presented. It includes an indirect check of the merit of the Gaussian approximation for the local density and a new way to inferring values of the thermodynamic ...

THERMODYNAMIC PROPERTIES OF BCC-FE TO MELTING TEMPERATURE AND PRESSURE TO 15 GPA

open access: yesГеодинамика и тектонофизика, 2015
Based on Helmholtz’s free energy, an equation of state of iron (bcc-Fe) is constructed with simultaneous optimization of ultrasonic, X-ray diffraction, dilatometric, and thermochemical measurements in the temperature range from 100 K to the melting ...
