Magnetohydrodynamic ferrofluid radiation and free convection heat transfer is investigated numerically
using Control Volume based Finite Element Method (CVFEM). Nanofluid viscosity is a function of magnetic
field strength. Roles of Radiation parameter ðRdÞ, inclination angle ðnÞ, Fe3O4-water volume fraction
ð/Þ, Hartmann ðHaÞ and Rayleigh ðRaÞ numbers are illustrated. A formula for average Nusselt number is
derived. Results proved that Nusselt number augments for larger buoyancy forces and radiation parameter.
Nusselt number decays through rise of Lorentz forces. Rate of heat transfer augments when inclination
angle is increased
