Abstract This article analyzes the mixed convection flow of magnetohydrodynamic (MHD) nanofluid. Water based nanofluid comprising silver and copper as nanoparticles is used. Fluid fills the porous space. Heat transfer analysis is carried out in the presence of nonlinear thermal radiation. Ordinary differential equations are formed by using suitable transformations. Convergent series solutions are obtained. Influence of involved parameters on velocity and temperature are analyzed graphically. Calculations for skin friction coefficient and Nusselt number are evaluated and examined for the pertinent parameters. It is observed that velocity profiles for both nanofluids show decreasing behavior for Hartman number and angle of inclination. Temperature profile enhances for increasing temperature ratio parameter and radiation parameter in copper water nanofluid. Skin friction coefficient and Nusselt number are increasing functions of mixed convection parameter. However the effects of silver nanofluid dominant for skin friction while copper nanofluid dominant over silver nanofluid for local Nusselt number.
