The enhancement of the thermal conductivity of water in the presence of Alumina (Al2O3) using the employed surfactant, as the dispersant, is presented in this study. The volume concentration of Alumina–water nanofluids is below 0.2 vol.%. With the addition of dispersant and surfactant, the thermal conductivity of the produced nanofluids reveals a time-dependent characteristic. The thermal conductivity, considerably steady at the starting point of measurement, increases gradually with elapsed time. The results indicate that Alumina–water nanofluids with low concentration of nanoparticles have noticeably higher thermal conductivities than the water-base fluid without Alumina. For Al2O3 nanoparticles at a volume fraction of 0.001 (0.1 vol.%), thermal conductivity was enhanced by up to 18.4%.
