Nanofluids are relatively new materials that are composed of liquids containing solid nanoparticles ranging from 1-100 nm. This study examined the thermal conductivity of Al2O3 (aluminum oxide)-H2O nanofluids in water under multiple pH and sodium dodecylbenzenesulfonate (SDBS) conditions. A transient plane source (TPS) was used to measure the thermal conductivities of the samples. It was found that when the pH of the nanofluid reached approximately 8.0, the solution ...
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....
