Résumé:
A numerical study has been performed by using single phase method on the
convective heat transfer of Cu/water and Al2O3/water nanofluids flowing through a square
microchannel under the laminar flow conditions (nanofluids are liquid suspensions of nanosized
particles). The effects of nanoparticles concentrations and Reynolds number are
investigated on the flow and the convective heat transfer behaviour. The results obtained by
the FLUENT software show that the presence of nanoparticles in the base fluid results in a
considerable increase of heat transfer. Heat transfer coefficient increases by increasing the
concentration of nanoparticles in nanofluid and Reynolds number
