Influence of interparticle interactions on diffusion processes in magnetic fluids

The diffusion coefficient is calculated for a concentrated magnetic fluid in the absence of a magnetic field, taking into account the many-body correlations. The ferroparticle density distribution in a gravitational field is determined using both Monte Carlo simulations and theoretical modeling. Numerical and theoretical results are in good agreement. © 2010 Published by Elsevier Ltd.This research has been carried out within the financial support of RFBR Grant No. 08-02-00647 and 10-01-96038; AVCP No 2.1.1/1535; FASI 02.740.11.0202; Project of the Analytical departmental special programm DSP 2.1.1/4463 and Grant of President of RF MK-1673.2010.2
