eat transfer fluid is one of the critical parameters that
affects the cost and size of thermal systems. Different
research groups around theworld have acknowledged the need
to develop new classes of fluids with enhanced heat transfer
capabilities. Many researchers have developed nanofluids using
nanoparticles, and they have shown a significant enhancement
inheattransfer.Duetotheirhighthermalandphysicalproperties,
the addition of nanomaterials can remarkably improve the
thermo-physical properties of a base fluid. Such a fluid contains
suspended nanoparticles called “nanofluids”. Nanofluids are a
new generation of liquids used for heat energy transport and
can be employed as heat transfer fluids in heat exchangers in
place of pure single-phase fluids. The most important reason
for enhancing nanofluids’ heat transfer is to accommodate
high heat fluxes and then reduce the size and cost of thermal
systems, thus conserving energy and materials. In the last
several years, many researchers have attempted to develop
heat transfer enhancement methods. Many nanomaterials,
such as Cu, CuO, Al

O

, SiO

, CNTs and graphene have been
used to improve the heat transfer properties of the base fluid.
Carbon nanomaterials have gained significant attention over
the last decade where the most eye-catching features of these
structures are their thermal properties, which can permit future
applications in thermal science and engineering. CNTs and
graphene nanoparticles have unusual heat transfer properties.
In the lengthwise direction, they show excellent heat transfer
performance. They also possess remarkable thermal properties
with ultra-high thermal conductivity (2000–3000 Wm
-1
K

),
which is much higher than those of metallic nanoparticles. CNTs
and GN can be dispersed homogenously in conventional heat
transfer fluids. Recent research has demonstrated that there is
a substantial increase in the thermal conductivities of different
CNT nanofluids in comparison to their base fluids. In general,
research on CNTs and GN nanofluids has blossomed in many
different directions and has attracted a great deal of attention.
