Ni-coated single-walled carbon nanotubes (SWNTs) were dispersed in four fluids (of varying viscosities) to create four different nanofluids. Due to the magnetic properties of the coated nanotubes the researchers induced a magnetic field to increase the thermal conductivity of the nanofluids. The increase in thermal conductivity was due to the alignment of the carbon nanotubes into chains due to the magnetic field. A Thermal Constants Analyzer was used to measure ...
