Continuum percolation thresholds for mixtures of spheres of di$erent sizes
نویسندگان
چکیده
Using Monte-Carlo simulations, we 4nd the continuum percolation threshold of a threedimensional mixture of spheres of two di$erent sizes. We 4x the value of r, the ratio of the volume of the smaller sphere to the volume of the larger sphere, and determine the percolation threshold for various values of x, the ratio of the number of larger objects to the number of total objects. The critical volume fraction increases from c=0:28955± 0:00007 for equal-sized spheres to a maximum of max c = 0:29731± 0:00007 for x ≈ 0:11, an increase of 2.7%. c © 2002 Elsevier Science B.V.

Series expansions for clustering in continuum-percolation models with interactions
The low-density expansions of the concentration of monomers, dimers, trimers, and the mean cluster size are computed exactly, up through three-body cluster integrals, for a continuumpercolation model of spheres characterized by both exclusion-volume repulsions and shortrange attractions. The compactness of trimers for our model is studied in the dilute limit. Interestingly, the [1,1] Pade appro...
متن کاملPrecise determination of the critical threshold and exponents in a three-dimensional continuum percolation model
We present a large-scale computer simulation of the prototypical three-dimensional continuum percolation model consisting of a distribution of overlapping (spatially uncorrelated) spheres. By using simulations of up to 105 particles and studying the finite-size scaling of various effective percolation thresholds, we obtain a value of pc = 0.2895± 0.0005. This value is significantly smaller than...
متن کاملPair connectedness and mean cluster size for continuum-percolation models: Computer-simulation results
We devise a new algorithm to obtain the pair-connectedness function Per) for continuumpercolation models from computer simulations. It is shown to converge rapidly to the infinitesystem limit, even near the percolation threshold, thus providing accurate estimates of Per) for a wide range of densities. We specifically consider an interpenetrable-particle model (referred to as the penetrable-conc...
متن کاملPrecise determination of the void percolation threshold for two distributions of overlapping spheres
The void percolation threshold is calculated for a distribution of overlapping spheres with equal radii, and for a binary-sized distribution of overlapping spheres, where half of the spheres have radii twice as large as the other half. Using systems much larger than previous work, we determine a much more precise value for the percolation thresholds and correlation length exponent. The value of...
متن کاملA New Mixing Rule for Mixtures of Hard Spheres
A mixing rule for the mixtures of hard-spheres is presented which can be reduced to the standard van der Waals mixing rule at low densities. The effectiveness of the mixing rule for the size and energy parameters of lennard-Jones fluid are examined by combining them with an equation of state to calculate thermodynamic properties. The results of calculation are compared with the molecular dy...
