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 ...
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 ...
