Abstract
In the present work, we studied a nonsimilar solution of steady forced convection boundary layer flow and heat transfer of a nanofluid past a stretching horizontal plate. One-phase model has been used for this study. The nonsimilarity equations are solved numerically. We considered a nanofluid consists of AL 2 O 3 as a nanoparticles and water as a base fluid. The volume fraction of nanoparticles is considered in the range 0 ≤ ? ≤ 0.2. with prandtl number pr = 6.2 for the water working as a regular fluid. The parameters which governing the solution are volume fraction of nanoparticles , stretching plate parameter ξ and power law index N . We investigated the effect of these parameters on the skin friction coefficient, Nusselt number, velocity and temperature profiles. We found that heat transfer rate and skin fraction increased when ? increased. On the other hand, we concluded that the increase in ξ and N made heat transfer rate increases and skin fraction decreases.
