A lattice Boltzmann analysis of the effects of the internal angular momentum on rheology of magnetic fluids Original Research Article

We study the rheological properties of the magnetic fluids with the internal angular momentum, using a new lattice Boltzmann model. By the appropriate extension of the lattice Boltzmann scheme for magnetohydrodynamics, it is possible to deal with the internal angular momentum caused by the magnetic dipole moment efficiently. This model is suitable for a wide use for simulating various behaviors of magnetic fluids with the internal angular momentum. We present here a two-dimensional lattice Boltzmann analysis of the effects of internal angular momentum in magnetic fluids in order to understand the rheological properties of the magnetic colloid driven by the external magnetic field.
