A numerical analysis is performed on buoyancy and magnetic effects on a steady two-dimensional boundary layer flow of an electrically conducting water-based nanofluid containing three different types of nanoparticles: copper (Cu), aluminium oxide (Al2O3), and titanium dioxide (TiO2) past a convectively heated porous vertical plate with variable suction. A similarity transformation was used to convert the governing partial differential equations to a system of nonlinear ordinary differential equations. A numerical shooting technique with a fourth-order Runge-Kutta-Fehlberg integration scheme was used to solve the boundary value problem. The effects of the type of nanoparticle, solid volume fraction phi, Hartmann number Ha, Grashof number Gr, Eckert number Ec, suction/injection parameter f(w), and Biot number Bi on the flow field, temperature, skin friction coefficient and heat transfer rate are presented graphically and then discussed quantitatively.
