Nanofluids are dilute liquid suspensions of nanoparticles
with at least one critical dimension smaller than (100 nm).
Nowadays, more attention were considered to this new type
of composite material because of its enhanced properties and
behavior associated with heat transfer. The main problems
of using such suspensions are the rapid settling of particles,
clogging of flow channels, and increased pressure drop in
the fluid. Nanoparticles are also suitable for use in microsystems
because they are many orders of magnitude smaller
than themicrosystems [1].
