Abstract: 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 neared an optimal value. Therefore, by optimizing both pH and SDBS concentration of the nanofluid, it is possible to enhance its thermal properties, for use in applications in the electronic, transportation and heating fields.
