In this work, the hydrodynamic and thermal behaviors of the laminar forced convection flow of nanofluids inside a uniformly heated tube have been numerically investigated. Results, as obtained for water-γAl2O3 and Ethylene Glycol-γAl2O3 mixtures, have eloquently revealed that the inclusion of nanoparticles has produced a considerable improvement of the heat transfer coefficient, which clearly becomes more important with an augmentation of the particle concentration. However, the presence of particles has induced drastic effects on the wall shear stress that remarkably increases with the particle volume concentration. Among the nanofluids studied, Ethylene Glycol-γAl2O3 clearly offers higher heat transfer enhancement; it is also the one for which more pronounced adverse effects on the wall friction could be expected. Results have also shown that, in general, the heat transfer enhancement also increases considerably with an augmentation of the flow Reynolds number. A correlation has been provided for computing the Nusselt number for the nanofluids considered in terms of the particle volume concentration, the Reynolds and the Prandtl numbers.
