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 thermal conductivity also increases because higher PH means more surface charges which increase conductivity. As the SDBS concentration is increased the thermal conductivity slightly increases ...
The field of nanofluids is relatively new, however researchers in this article aimed to research their thermal conductivity and dispersion behaviours. A nanofluid consists of free-floating, solid nanoparticles suspended in a base fluid. Specifically, Al2O3-H2O nanofluids were investigated in this study. Using a thermal constants analyzer, the thermal conductivities of various modifications of nanofluids were measured. Research concluded that pH and concentrations of SDBS dispersants have a ...
Thermal conductivity of heating and cooling fluids with added nanoparticles dubbed 'nanofluids' are used as potential to improve the efficiency of heat transfer fluids using a thermal constants analyser. The Thermal conductivity enhancements of Cu-H2O nanofluids are dependent on the weight fraction of nanoparticles, pH values and sodium dodecylbenzenesulfonate (SDBS) surfactant concentration of nano-suspensions. Combining both the pH and chemical surfactant is recommended to improve the thermal conductivity for ...
