Impact of Carbon Nanotube in the Heat Transfer Applications

The modern industrial development in heating, ventilation, and air-con-
ditioning (HVAC), industrial cooling, automobile cooling, microchip cooling,

phase change heat transfer and nuclear reactors has resulted in the urgent need
for performance improvement in heating and cooling applications. An efficient

heating and cooling system can be achieved by increasing the heat transfer pro-
cess, which is a significant task in the current scenario of the enormous energy

demand. Performance improvements in heating and cooling systems can be car-
ried out through various methods. Because of recent advances in nanotechnol-
ogy, researchers have tried a new idea of combining nanoparticles with a base

fluid to improve the fluid thermophysical properties. The liquid consists of bal-
anced nanoparticle sizes below 100 nm. Nanoparticles might be nanopowder or

nanoparticles like MWCNT (Multi-walled carbon nanotube), Al2
O3
, TiO2
, Cu,
and SiC. This idea of nanoparticle addition is introduced in the heat transfer
application to enlarge the convective heat transfer coefficient and enhance the
nanofluid and thermo-physical properties to study the opportunity of improving
the system performance.
