G0803 On the Hybrid-type Method of Brownian Dynamics and Lattice Boltzmann for Activating the Brownian Motion of Magnetic Particles

Abstract

We have discussed the feasibility of a hybrid-type method of Brownian dynamics and lattice Boltzmann for activating the Brownian motion of magnetic particles in a suspension composed of these particles. In this hybrid-type method, the random forces are added to the equations of motion of magnetic particles as in the usual Brownian dynamics. In order to activate the Brownian motion at a physically reasonable level, a viscosity-modifying method is introduced in adjusting the random displacements of the particles. This hybrid-type method with viscosity-modifying procedure is verified by comparing the present results with those of the Monte Carlo simulations.
