Abstract
The lattice Boltzmann approach is used to solve continuum equations
describing colloids of ferromagnetic particles (ferrofluids) in a
regime where the particle spins are in equilibrium with magnetic
torques. This limit of rapid spin adjustment yields a symmetric
total
stress tensor that is essential for a kinetic formulation based on
the
Boltzmann equation. The magnetisation equation is solved using a
vector-valued distribution analogous to the earlier treatment [J.
Comput. Phys. 179, 95]
of
the
induction equation in magnetohydrodynamics, but the details
are
rather more complex because the magnetisation equation is not in
conservation form except in a weakly magnetised limit.
