Abstract: This study aims to use Boron Nitride (BN) materials as thermo-conductive fillers to enhance the heat transfer in fluids. For this study, BN nanotubes, and nanospheres were added to fluids, to test for individual thermal enhancements. With the addition of BN nanotubes to water, the thermal conductivity of the fluid was enhanced by 2.6 times. Also noted, was the increase in conductivity of the fluid with the addition of BN nanospheres. As a test, nanotubes and nanospheres were collectively added to a fluid, to note their effects on the thermal conductivity of the fluid. This experiment showed the nanotube-nanosphere mixture was promising as a filler for fluids, as the thermal conductivity of the fluid increased, while the viscosity remained low.
