A numerical analysis is performed on the buoyancy and magnetic effects on a steady two-dimensional boundary layer flow of an electrically conducting incompressible Al2O3-water nanofluid past a convectively heated porous vertical plate with variable suction and no slip boundary condition using Ansys FLUENT 15.0. The effects of the solid volume fractions of nanoparticle, magnetic field strength (Hartmann number), buoyancy effect (Grashof number), suction/injection parameter, viscous dissipation parameter (Eckert number) and intensity of Newtonian heating (Biot number) on the dimensionless heat transfer rate (Frossling number) are discussed. Increasing solid volume fraction of alumina-water nanofluid and using low strength magnetic field enhances surface cooling effect compared to conventional base fluids. Suction parameter and buoyancy effect are found relatively better contributing parameters in enhancing heat transfer rates. The best heat transfer rate was noticed with Hartmann number of 10-15, nanofluid volume fraction of 0.2, Biot number of 0.12, Eckert number of 0.1, Grashof number of zero and suction parameter of one. Rate of heat transfer increases with increase in intensity of Newtonian heating, suction parameter and volume fraction of Al2O3 nanoparticles whereas heat transfer.
