In the present work we consider the growth of a very dilute concentration of anisotropic particles, nucleated with random orientations, in a matrix of growing spherical particles. It is assumed that the matrix particles obey the usual JMAK kinetics. We concentrate on describing the change in...

We have investigated the effects of substrate topography on the nucleation and growth behavior of 321 stainless steel (ss) films, introducing textured surfaces into mica substrates by the abrasion treatment. In this study, two groups of samples were prepared at three different sputtering time...

We present a model equation that describes nucleation and growth of hemispherical nanoclusters or islands deposited on a substrate for the small surface coverage case. The model is formulated in terms of a set of rate equations for the island sizes, combined with the time-dependent behavior of...

A new kinetic model for binary mixtures and its lattice Boltzmann (LB) discretization is formulated. In the hydrodynamic limit, the model recovers the Navier–Stokes and the Stefan–Maxwell binary diffusion equations, satisfies the indifferentiability principle, and is thermodynamically...

For binary mixtures with fixed concentrations of the species, various relationships between the surface tensions and the concentrations are briefly reviewed.

We have analyzed the rate of convergence of a series expansion, in terms of the density, of the ratio of the excess compressibility factor of fluid mixtures of additive hard spheres to that of a pure hard-sphere fluid with the same reduced density. The terms in the series can be obtained from...

We introduce new versions of lattice Boltzmann methods (LBM) for incompressible binary mixtures where fluctuations of total density are inhibited. As a test for the improved algorithms we consider the problem of phase separation of two-dimensional binary mixtures quenched from a disordered state...

A set of differential equations is established that determine the positions of the tielines for phase separation at constant temperature, provided the equation of state for a binary mixture is given in analytical form. Despite the fact that a large amount of work has been done on this problem,...

We generate exact mixing rules for dilute gaseous mixtures with nonconformal interactions by introducing an adequate effective potential. The general mixing rule leads to several approximations of the van der Waals type. The work uses nonconformal model pair potentials that accurately describe...

The transport coefficients for a disparate mass binary mixture are calculated as functions of the wave vector k and the frequency ω, taking as a starting point a kinetic model based on the Boltzmann equation. This allows us to study their behavior for short times and small distances when...
