Importance of Nanoparticles in Heat Transfer

The effect of nanoparticle applications in quite propitious in ameliorating the heat
transfer characteristics of base fluid in heat exchanger. The concept of adding SDBS
additives to the base fluid is to obtain better heat transfer and cooling characteristic.
The size of the catalyst (micro size or nanosize) added to the base fluid plays a
significant role in the improved base fluid properties. The information indicates that
addition of nanoparticles to any conventional coolant (such as water, ethylene glycol)
enhances the heat transfer rate and cooling rate favours reduced evaporation time and
leads to better characteristics. The physical properties of the base fluid and the
modified fluid formed by dispersing the nanoparticles by ultrasonic agitation.
Comparisons of the heat transfer of the fluid with and without the additive are also
presented. The heat transfer levels of base fluid are appreciably increased with the
addition of nanoparticles.
