This paper deals withsteady two dimensional laminar convection flow of nano fluid over aconvective heated inclined plate.Boungiorno model [VI] is employed that treats the nanofluid as a two-component mixture (base fluid plus nanoparticles), incorporating the effects of Brownian motion and thermophoresis.Byappropriate similarvariables, the governing nonlinear partial differential equations of flow are transformed to a set of nonlinear ordinary differential equations. Subsequently they are reduced to a first order system and integrated using Newton Raphson and adaptive Runge-Kutta methods. The computer codes are developed for this numerical analysis in Matlab environment. Dimensionless stream function (s), longitudinal velocity (s′), temperature (θ) and nano particle volume fraction (f) are computed and illustrated graphically for various values of thedimensionless parameters relevant to the present problem. The effects of the angle of inclination on longitudinal velocity (s′), temperature (θ) and nano particle volume fraction (f) are discussed. The results of the present simulation are in with good agreement with the previous reports available in literature.
