COMPARISON OF THE EQUATIONS OF STATE FROM JOULE-THOMSON COEFFICIENT [PDF]

Journal of Sciences, Islamic Republic of Iran, 2000
In the present work, we have examined the ability of some different equations of state in predicting the Joule-Thomson coefficient, ?J-T, of different fluids.

Scale without conformal symmetry in hydrodynamics

European Physical Journal C: Particles and Fields
Scale without conformal symmetry corresponds to an inhomogeneous conservation equation for the virial current sourced by the trace of the energy–momentum tensor. Fluids that are just scale-invariant differ qualitatively from their conformal counterparts,

The Liquid Density of Complex Liquid Mixtures [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1998
A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid ...

Evolution of a stellar system in the context of the virial equation

The virial equation is used to clarify the nature of the dynamic evolution of a stellar system. The methods used are based on analytical and numerical modeling of evolution, as well as on an approach long used in the nonlinear theory of oscillations.

AN EMPIRICAL VIRIAL-LIKE CUBIC EQUATION OF STATE FOR PHASE EQUILIBRIUM CALCULATIONS

, 1990
An empirical cubic equation of state(EOS) was obtained by truncating the virial expansion in reciprocal of molar volume after the third term. The constants of the EOS was generalized in terms of critical temperature, critical pressure and Pitzer's ...

Negative energy blowup results for the focusing Hartree hierarchy via identities of virial and localized virial type

, 2018
We establish virial and localized virial identities for solutions to the Hartree hierarchy, an infinite system of partial differential equations which arises in mathematical modeling of many body quantum systems.

The Duffin-Kemmer-Petiau equation (DKP) wavefunctions solutions according to the virial theorem for a spinless boson particle interacting with a potential V(r) = kr(n)

, 2016
The Duffin-Kemmer-Petiau (DKP) equation is written for a spinless boson particle interacting with a potential V(r) =kr(n). The written equation is redesigned for this potential according to the virial theorem.

Virial theorem from action principles

The virial theorem is derived from the action principle and variational method in classical and quantum mechanics by exploiting the scale invariance of the action and the Hamiltonian operator.
