A key assumption of The whole machinery used to study phase transitions and crit-ical phenomena can be used to understand how percolation … [13,14]): (4) a j(r,r)a j(r ,r)≥ a … This article deals with the critical exponents of random percolation. tell us that one should look for critical behavior. CRITICAL EXPONENTS FOR TWO-DIMENSIONAL PERCOLATION 733 lim ρ→∞ (3) a j(ρ,Rρ)=R−j(j+1)/6+o(1) whenR→∞. RESTRICTED PERCOLATION EXPONENTS 2373 On the hypercubic or spread-out lattices with d 2 , it is widely conjectured that P p c-almost surely there exists no infinite open cluster.Among others (see Section 1.2 below for background and references), this conjecture is proved in ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. The finite size scaling arguments are used for the connectivity to determine the dependency of the critical exponents on the power law exponent. In the context of percolation theory, a percolation transition is characterized by a set of universal critical exponents, which describe the fractal…. the exponent associated with the length scale of finite clusters, is 1 4. Deviations of critical exponents from the universal values investigated numerically. For infinite systems around the percolation threshold, p c ∞, the following power laws apply: (1) P (p) ∝ (p − p c ∞) β (2) ξ (p) ∝ (p − p c ∞) − υ where ξ is the correlation length which is a representative of the typical size of clusters and β and υ are two universal exponents called the connectivity exponent and correlation length exponent respectively. figure represents an estimate. • Crossingprobabilitiesenjoythefollowing(approximate)multiplicativity propertywithsomepositivec=const(j),providedr ≥ r ≥ r>j(cf.

These two shapes are the representative of the fractures in fracture reservoirs and the sandbodies in clastic reservoirs.

The standard percolation theory uses objects of the same size. Studying the connectivity of systems with a very broad size distribution is improved. In fact, near p c, several quanti-ties exhibit power-law behavior, and there are scaling laws relating the different critical exponents. The exponents are universal in the sense that they only depend on the type of percolation model and on the space … Copyright © 2013 Elsevier B.V. In this study, the effect of power law size distribution on the critical exponents of the percolation theory of the two dimensional models is investigated.

In the context of percolation theory, a percolation transition is characterized by a set of universal critical exponents, which describe the fractal properties of the percolating medium at large scales and sufficiently close to the transition.
