The chemical potentials of binary Lennard-Jones mixtures are calculated by means of the modified scaled particle Monte Carlo method (SP-MC) and using the conventional test particle procedure (TPI). Grand canonical Monte Carlo (GCMC) simulations are also performed as an independent verification...

Monte Carlo simulations are presented for a model of a symmetrical polymer mixture on the simple cubic lattice, modeling both polymers A, B by self-avoiding walks of NA=NB=N steps. If a pair of nearest-neighbor sites is taken by monomers of the same species, an energy Îµ is won. In the Monte...

A hybrid, semigrand ensemble is applied to the simulation of mixtures of very many components. The independent variables are temperature, density, and the distribution of activity ratios. The system samples different compositions, with particles changing species identities during the simulation....

- Phase stability of dense charged hard sphere fluid mixtures. Caccamo, C.; Malescio, G. // Journal of Chemical Physics;1/15/1989, Vol. 90 Issue 2, p1091
The mean spherical approximation (MSA), the hypernetted-chain (HNC) approximation, and Monte Carlo (MC) calculations are used in order to investigate the phase stability of dense charged hard sphere fluid mixtures. According to the MSA, spinodal decomposition occurs in these systems in a certain...

Monte Carlo (MC) simulations are used to determine the properties of two different binary multi-Yukawa mixtures studied previously through a quasianalytic Yukawa-MSA (mean spherical approximation) algorithm [Arrieta, Jedrzejek, and Marsh, J. Chem. Phys. 95 XXXX (1991)]. These mixtures are...

A new molecular model, called the generalized hard-sphere, or GHS model, is introduced. This model contains, as a special case, the variable hard-sphere (VHS) model of Bird [Rarefied Gas Dynamics, edited by S. S. Fisher (AIAA, New York, 1981), Part 1, p. 239] and is capable of reproducing all of...
