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 ...
The Transient Plane Source method was used in this research article to measure the thermal conductivity of an Ionanofluid, highly stable graphene (GE)-based nanofluid, at various temperatures. Researchers took special note of the effects of temperature, GE loading, presence of multi-walled carbon nanotubes (MWCNTs), on the thermal conductivity of the nanofluid. Through experimental testing, it was determined that the nanofluid elicited a higher thermal conductivity, as compared to its ...
This research article proposes the use of a thermal constants analyzer to measure thermal properties of relatively thin samples. Five different metallic samples containing copper, aluminum and brass were used to test the accuracy of the new and improved method. Previously, this method has been used to test the thermal properties of thin metallic sheets, however with the new and improved method, it is possible to measure samples with thicknesses ...
