Nano-fluids have solved this constraint because of their remarkable heat
transfer abilities.A fluid which contains nanometer-sized particles
(1–100 nm in one dimension) is called nanofluid. Comparing to
base fluids, nanofluids enhance the rate of heat transfer.Hence,
they have a wide range of utility in industry,thermal generation,
transportation and microelectronics.Adding nanometer-sized particles to a fluid was initially investigated byChoi in1995 , in
which the results revealed better thermal conductivity.
