Abstract: 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 of the nanofluid. An optimal pH value and SDBS concentration must be reached in order to attain the highest form of stability and thermal conductivity.
