要約

This paper aims to study the convective heat transfer behaviour of aqueous suspensions of nanoparticles flowing through a horizontal tube heated under constant heat flux condition. Consideration is given to the effects of nanoparticle concentration and Reynolds number on heat transfer enhancement in the turbulent flow region. It is found that (i) heat transfer enhancement is caused by suspending nanoparticles, so that maximum value of the Nusselt number is over twice than that of the pure working fluid, (ii) graphene-oxide-nanofluid developed here is non-Newtonian fluid, and (iii) but the pressure drop for graphene-oxide-nanofluid is almost the same as that of the pure working fluid, because volume fraction of particles is less than 1.0%.
