In the present paper, forced laminar flow of Al2O3/water and Al2O3/Ethylene Glycol (EG) nanofluids inside
the tube (heated partially and uniformly) were numerically investigated by using single phase method. The
effects of nanoparticles concentrations (0 - 5%) and base fluids are investigated on the flow and the convective
heat transfer behaviour.
The results obtained by the FLUENT software show that the enhancement in heat transfer is considerable
when there are the nanoparticles in the base fluid. The wall temperature decreases with the increase in
nanoparticles concentration, indicating that the heat transfer coefficient increases by increasing the concentration
of nanoparticles in nanofluids. The Al2O3/Ethylene Glycol nanofluid has the highest Nusselt number than
Al2O3/water nanofluid
