Effect of size distribution on ferrofluid configuration: A Monte Carlo simulation

Dipole-dipole interaction plays a major role in governing the pattern forma tion phenomena in a ferrofluid. Usually this interaction varies as the conc entration is changed. A theoretical analysis on the effect of dipole-dipole interaction on a ferrofluid configuration by varying the size distribution of the particles is being presented here. Two types of distributions viz., log normal and flat top are chosen for the study. The simulations were car ried out using a simple model incorporated in the Monte Carlo simulation te chnique. Results of the simulations are compared with those experimentally observed.
