A magnetic field coupling lattice Boltzmann model and its application on the merging process of multiple-ferrofluid-droplet system

作者：

Highlights：

• A magnetic field coupling LB model is proposed for magnetic multiphase flows.

• The magnetic effect is physically described by a surface force derived from Lorentz force law.

• The elongation of ferrofluid droplet is well consistent with the experiment.

• The merging process of the multiple-ferrofluid-droplet system is investigated.
