چکیده

In this article, laminar flow and convection heat transfer of water–alumina nanofluid
in a rectangular microchannel have been investigated numerically. Because of the existence of
slip velocity between nanoparticles and base fluid, the mixture model is used and results are
compared with the single-phase model. The results indicate that using nanofluids can enhance
convective heat transfer and pressure drop in a microchannel in comparison with pure water.
Also, the enhancement of convection heat transfer is higher in the developing region and the
difference of the mixture model and single-phase model is slightly great in this region, but in fully
developed region the differences are very low.
