This article evaluates the thermal conductivity of heat transfer nanofluids containing nickel coated single wall carbon nanotubes. The results concluded that with the introduction of a magnetic field, the thermal conductivity of the heat transfer nanofluid is improved. Researchers attribute this improved thermal conductivity to the ability of the nickel coated nanotubes to form aligned chains under the force of a magnetic field, allowing for better contact and ultimately a ...
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 ...
