Nanofluids are considered to offer important advantages over conventional heat transfer fluids. In the present
paper the governing continuity, momentum and energy equations for pure water and water based alumina nanofluid
flowing on a semi-infinite slab has been solved, applying finite element by Ritz-Galerkin approach. Compared with
water, the heat transfer behavior of nanofluid showed a considerable enhancement in convective heat transfer with
increasing particle volume fraction of nanofluid. If the particle volume fraction is increased to 5%, the rate of heat
transfer increases almost 9% compared with that of pure water, which is in good agreement with numerical solutions.
