Abstract: The effects of particle size/shape, base fluid, and volumetric concentration on the thermal conductivity of nanofluids has been studied. It was found that decreasing the particle size leads to an increased thermal conductivity, and that using water as a base fluid led to the greatest enhancement of thermal conductivity. The effects of gravity, Brownian motion, and thermophoresis on particle motion were also investigated and it was found that gravity had a significant impact on the thermal conductivity of these nanofluids due to rapid settling of the nanoparticles, resulting in a decreased thermal conductivity.
