Abstract
The present study considered the thermal convection of ferrofluids along a flat plate subject to uniform heat flux and slip velocity in the presence of radiation with a magnetic field applied in the transverse direction. Two different types of ferrofluids are considered: one magnetic nanoparticle (Fe_3 O_4) and one non-magnetic nanoparticle (TiO_2)that are incorporated within two different kinds of base fluids, water and kerosene oil. Numerical solutions are obtained using a finite difference scheme named Keller-Box method for each mixture of base fluids with Fe_3 O_4 and TiO_2 for the variations of volume fraction, magnetic field, velocity slip, radiation and suction and the results are compared with the available data. The effects of different parameters are presented graphically and discussed.The variation of skin friction coefficient and heat transfer rate, i.e. the Nusselt Number are also shown in tabular form.

Keywords
Ferrofluids, Keller-Box method, velocity slip, skin friction coefficient, heat transfer rate.
