Application of the hybrid-type method of Brownian dynamics and lattice Boltzmann to magnetic particle suspensions

We have investigated the feasibility of the hybrid-type method of lattice Boltzmann and Brownian dynamics as a simulation technique for a magnetic particle suspension. To do so, we have addressed aggregation phenomena in thermodynamic equilibrium and have compared the present results with those of M...
