Second order virial coefficients from phase diagrams
The prediction of phase separation is essential to understand and control the properties of food systems. In this work, an existing theoretical model for describing phase separation between binary mixtures of hydrocolloids, using a virial approach up to ...

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).

Calculation of Virial Coefficients and Their Uses [PDF]
This work is centers on the classical statistical derivation of thermodynamic properties of a system from its pair potential through the calculation of virial coefficients and also develops a useful method for modeling systems with the square-well ...

An investigation of virial coefficients of gases [PDF]
The most widely used experimental method for studying the forces between pairs of molecules is the determination of the second compressibility virial coefficient, B, defined by: z = Pvm/RT = 1 + B/Vm + C/V2 + . . . For non-polar gases at temperatures

Virial Coefficients for Thermodynamic Systems with Hill Pseudopotential [PDF]
Temperature dependences of the 2-nd, 3-d and 4-th virial coefficients for chemically aggressive environments are analyzed. Their calculation is performed for several different pair interaction potentials and built on them Hill pseudopotentials.

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 ...

We calculate the fourth cluster coefficients of the homogeneous unitary spin 1/2 Fermi gas as functions of the internal-state mass ratio, over intervals constrained by the 3- or 4-body Efimov effect.
