The researchers in this paper were the first to report that the thermal conductivity of the heat transfer nanofluids has the ability to be enhanced by an external magnetic field. This is possible due to carbon nanotubes and magnetic-field-sensitive nanoparticles of Fe2O3. It was discovered that the Fe2O3 nanoparticles form chains when exposed to magnetic fields, which allows the nanotubes to connect. As the nanotubes connect, the thermal ...
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 ...
