Nanofluids are colloidal suspensions of nanometer-sized particles (metals, metallic oxides or carbon nanotubes) in a base fluid (polar or non-polar).Nanofluids have interesting properties that make them useful especially in the design of compact heat transfer equipment.Laminar convective heat transfer of nanofluids (water, Al2O3) in a square and circular ducts has been studied numerically using the software ANSYS/FLUENT 12.1.

Results for the Nusselt number, skin coefficient Hallway Runner friction, temperature and velocity profiles are presented for ORG CITRUS DEODORANT SPRAY four nanoparticle volume fractions (j = 0 - 20%) and Reynolds numbers (Re = 800, 1300 and 2000).For the studied Re numbers, Nu is decreased by 12% and 10%, when j is increased from 0% to 10% and from 10% to 20%, respectively.Regard to the skin friction factor, the obtained value is increased around a 30% when j is increased 10%.
