Nano-inclusions are thermally conductive particles that improve the thermal conductivity of liquid mediums. In this paper, the thermal properties of Mg2Si were evaluated after the addition of TiO2 nanoparticles. An instrument measured the thermal conductivity of the nanofluid using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluid was the highest at lower temperatures, and did not improve with the addition of the ...
This study looks at the effects of pH on heat transfer, among other things, of nanofluids. Over 20% enhancement of thermal conductivity was noted with nanofluids containing 3wt% zirconium dioxide and titanium dioxide. Also noted, was the influence of pH on the stability of the nanofluids. The Derjaguin-Landau-Verwey-Overbeek theory states that nanoparticles become unstable, form clusters and precipitate, when their pH is near the isoelectric point. This leads to large clusters ...
