This experiment outlined an investigation into heat transfer of two water-based nanofluids; H2O-Al2O3 and H2O-Cu. The absorbency and thermal conductivity of both nanofluids was measured under various pH values and sodium dodecylbenzene sulfonate (SDBS) concentrations, to determine whether an effect on heat transfer is present. The results concluded that the stability and thermal conductivity of the nanofluids are greatly dependent on the pH values and SDBS concentrations ...
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 ...
