Abstract

In this study, heat transfer of ferrofluid Fe3O4 − H2O generated by Rayleigh-Bénard convection in a square cavity is studied numerically in the presence of a vertical uniform magnetic field. The effect of the governing parameters, such as the Rayleigh number (𝑅𝑎 = 103 − 105), the volume fraction of nanoparticles (φ = 0 − 4%) and the Hartmann number (Ha = 0 − 100), is studied using the Lattice Boltzmann Method (LBM). The results obtained show the existence of up to three different solutions for values of Ha less than some threshold. The obtained solutions have different ranges of existence and generate different amounts of heat transfer.
