ABSTRACT={A 2-D numerical investigation was carried out to study the nanofluid flow and heat transfer inside a horizontal ribbed micro-channel. The alumina oxide nanoparticles were suspended in water as based fluid at different volume fraction 0, 2 and 4%. The finite volume method was used to solve the continuity, momentum and energy equations. The effects of different parameters such as nanoparticles volume fraction, Reynolds number, and the larger of ribs has been reported. It was found that the heat transfer and the Poiseuille number increases with increasing nanoparticles volume fraction and Reynolds number. Using a small rib improves the heat transfer. Increasing ribs number enhances the heat transfer rate.}}
