Second Virial Coefficients for Dimethyl Ether [PDF]
Dimethyl ether (DME) is a clean and economical alternative fuel. In addition, it is also an ozone-friendly refrigerant. Burnett measurements were carried out at temperatures from (344 to 393) K and at pressures from (0.055 to 4.015) MPa. A total of 138 experimental points, taken along 15 isotherms and 12 different temperatures, were obtained.

Modifications to the traditional Onsager theory for modeling isotropic–nematic phase transitions in hard prolate spheroidal systems are presented. Pure component systems are used to identify the need to update the Lee–Parsons resummation term.

An EOS for the Lennard-Jones fluid: A virial expansion approach
A large number (>30 000) of Monte Carlo simulations in range of 0.002–1.41 ρ* and T* ≤ 25 (* for reduced, dimensionless) was performed, producing a dense grid of state points for the internal energy U* and pressure p*.

Determination of the Second Virial Coefficient for Binary Mixtures of Ar with CH4 and CO using Van der Waals and Dieterici Models [PDF]
In this paper, we calculate the second virial coefficient for binary mixtures of Ar with CH4 and CO in order to evaluate the performance of equations of state (EOSs).

THE FOURTH VIRIAL COEFFICIENT OF ANYONS [PDF]
We have computed by a Monte Carlo method the fourth virial coefficient of free anyons, as a function of the statistics angle θ. It can be fitted by a four term Fourier series, in which two coefficients are fixed by the known perturbative results at the boson and fermion points.

DEFORMED GAS OF p, q-BOSONS: VIRIAL EXPANSION AND VIRIAL COEFFICIENTS [PDF]
In the study of many-particle systems both the interaction of particles can be essential and such feature as their internal (composite) structure. To describe these aspects, the theory of deformed oscillators is very efficient. Viewing the particles as p, q-deformed bosons, in the corresponding p, q-Bose gas model we obtain in explicit form virial ...

On extrapolation of virial coefficients of hard spheres
Several methods of extrapolating the virial coefficients, including those proposed in this work, are discussed. The methods are demonstrated on predicting higher virial coefficients of one-component hard spheres.

Second Virial Coefficients for Nonspherical Molecules and Their Experimental Measurements [PDF]
The virial coefficients can be obtained from statistical mechanics in connection with the intermolecular potentials. The intermolecular potential of polyatomic molecules is usually assumed to consist of a spherically symmetric component plus a ...
