The thermal conductivity and dynamic viscosity of Al2O3-ethylene glycol and TiO2-ethylene glycol nanofluids have been determined as a function of the nanoparticle volume fraction (from 1 to 3 %) and temperature. It was determined that the thermal conductivity increased with increasing temperature as well as ...
This study investigates the properties of a material to be used as an energy storage medium that can use energy stored from the summer months, and then release it during the winter. The proposed material uses a graphite foam, with ZnO coatings with a flower ...
The addition of Cu nanoparticles to water was studied at different pH values and different dispersant concentrations by the measurement of zeta potential and absorbency. Thermal conductivity was measured. It was found that the ideal properties of the nanofluid were obtained at pH 9.5....
Four different cationic surfactants were allowed to adsorb on boron nitride (BN) over the pH range of 5.5 to 8 in separate experiments. The authors talk about the orientation of the surfactant relative to the BN particles. The use of these surfactants has changed the partial ionic ...
This article looks at the thermal properties of titanium oxide (TiO2) based nanofluids and their applications as thermal vectors. The nanoparticle size was studied by dynamic light scattering (DLS) and the stability was measured by Zeta potential. The concentrations of TiO2 used ranged from 1 to 35% ...
