Abstract
In this paper, we report for the first time, thermal conductivity behavior of nanofluids
containing decorated MWCNTs with different amount of TiO2 nanoparticles. TEM image
confirmed that the outer surface of MWCNTs successfully decorated with TiO2
nanoparticles. The results of thermal conductivity behavior of nanofluids revealed that
the thermal conductivity and enhancement ratio of thermal conductivity of MWCNTsTiO2 at different amount of TiO2 nanoparticles are higher than those of TiO2 and
MWCNTs nanofluids. Temperature and weight fraction dependence study also shows that
the thermal conductivity of all nanofluids increases with temperature and weight fraction.
However, the influence of temperature is more significant than that of weight fraction.
We also found that decreasing amount ofTiO2 nanoparticles which introduce the outer
surface of MWCNTs leads to the augmentation of thermal conductivity of nanofluids
containing MWCNTs-TiO2.
