P‎air correlation function and its role in characterizing a system of randomly dispersed particles

چکیده مقاله

The pair correlation function (p.c.f.) is a statistical mechanical tool that quantifies the density variation as a function of distance from a reference particle in a system of randomly dispersed particles and is usually used to describe quantitatively, for example, the internal structure of fluids. In this paper, after recalling the p.c.f function to study the interaction behaviour between particles, i.e. attraction, repulsion or independence, different particle sys-tems are simulated in 2D and the estimated p.c.fs are interpreted.
