In this work, Polyalphaolefin oil-based hybrid nanofluid containing Fe3O4/MWCNT
nanocomposite has been prepared to consider the impact of volume fraction on
thermal conductivity through graphical representation. The heat transfer of the
prepared nanofluids is investigated via adjusting the surface morphology, molar
ratios and size of the nanocomposite. Phase and composition of the synthesized
sample was inspected through XRD and FTIR spectroscopy. The average crystallite
size was observed to be 7.74 nm from Debye-Scherrer equation. Thermophysical
parameters such as diffusivity, specific heat and thermal conductivity were
measured through transient plane source method. The sample showed 2%
enhancement in thermal conductivity with addition of nanocomposite as compared
to pure polyalphaolefin oil for 0.7 wt.% at 50℃ and this value declined when shifted
towards very high temperatures. Similarly, thermal diffusivity and specific heat also
showed a linear trend as a function of volume fraction. This shows that the prepared
nanofluid contains high stability and thermal conductivity as compared to
conventional lubricant (i.e., PAO) and has potential in heat transfer applications as
a lubricant and heat transfer fluid.
