A numerical study is carried out for mixed convection heat transfer in a ventilated cavity with injection or suction of Al2O3-water Nanofluid. The bottom wall is subjected to a sinusoidal hot temperature profile whereas the other boundaries are assumed to be thermally insulated. The effects of various design parameters such as Reynolds number (200 £ Re £ 5000), nanoparticles concentration, (fi £ 0.1), and mode of imposed external flow (injection and suction) on the fluid flow and heat transfer inside the cavity are investigated.
