Enhancing thermal conductivity of water by using TiC nanopowder with cryogenic treatment.

The thermal conductivity of TiC/water nanofluid is found out at different weight fractions of 0.1%, 0.2% and 0.3% and the results are compared with water (base fluid). It has been shown that the thermal conductivity of TiC/water nanofluid is improved when compared with water. Then, an inexpensive cryogenic treatment is adopted to find the thermal conductivity of cryo-TiC/water nanofluid. It has been found that the cryogenic treatment on TiC nanopowder is further enhancing the thermal conductivity of TiC/water nanofluid. The lattice vibration of the particles is responsible for the improvement of thermal conductivity. [ABSTRACT FROM AUTHOR]
