This study aimed to improve the heat transfer capabilities of water-based nanofluids, by varying the concentration of sodium dodecylbenzene sulfonate (SDBS), a chemical surfactant, as well as by altering the pH. It is said that the thermal conductivity and stability of nanofluids are directly related and are also greatly influenced by pH and chemical surfactant concentration. The water-based nanofluids displayed higher thermal conductivity values as the pH and SDBS concentration ...
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 ...
