ABSTRACT
A further important contribution to the cooling issue may be derived by the replacement of traditional heat transfer fluids, such as water, ethylene glycol, and mineral oils, with nanofluids. These are a new type of heat transfer fluids consisting of colloidal suspensions of nanoparticles, whose effective thermal conductivity has been demonstrated to be higher than that of the corresponding pure base liquid. Actually, since their introduction, nanofluids have attracted the attention of the heat transfer community, as reflected by the large amount of experimental and numerical papers published up to now on forced convection applications, whose common conclusion is that nanoparticle suspensions have a valuable potential for heat transfer enhancement-see, for example, the recent review article compiled by Hussein et al. [1].
