Abstract: The thermal conductivity of heat transfer nanofluids has been determined to increase by 10%, when containing metal oxide nanoparticles and carbon nanotubes. The fluid viscosity of the nanofluids is relatively the same as water, and therefore cannot not account for the increase in thermal conductivity. However, the fashion in which the metal oxide particles conglomerate within the fluid could be a potential explanation for the spike. Results show that under the influence of a strong outside magnetic field, the thermal conductivity value decreases. The thermal conductivity value also decreases when the pH is shifted from 7 to 11.45.
