Abstract: 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 great impact on the thermal conductivity of the nanofluid. The nanofluid had a considerably higher thermal conductivity than the base fluid itself, and with a weight fraction of 0.0015 (0.15%) of Al2O3, the thermal conductivity increased by 10%.
