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 (...
This study investigates the effect changing the PH of a copper nanofluid and sodium dodecylbenzenesulfonate (SDBS) surfactant concentration has on the thermal conductivity of the nanofluid. The thermal conductivity was determined through the Hot Disk Transient Plane (TPS) method. As the PH is increased the ...
A series of Al2O3-water nanofluids were synthesized and their thermal conductivities were evaluated under different pH values and concentrations of surfactant (SDBS) using the Thermal Constants Analyzer. All the properties studied were found to have a strong effect on the measured thermal conductivity. ...
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....
