Heat transfer augmentation in engineering thermal devices by incorporating nanofluid as heat transfer medium: An extensive review study

Abstract

To acknowledge the prominent significance of new generation heat transfer medium (Nanofluid) in current engineering era, we have demonstrated the extensive literature study to shed light on its every crucial aspect. Heat transfer enhancement in engineering thermal devices is carried out by incorporating Active and Passive techniques. Passive techniques such as modifying heat transfer surfaces, inclusion of obstacles, replacement of base fluid with various nanofluids etc. impart substantial role in augmentation of heat transfer performance. We have extensively elaborated the noteworthy impact of nanofluids on thermal performance of heat exchangers, automotive radiators, refrigeration and air-conditioning system, and solar thermal convection. Furthermore, downsides of nanofluid have also been elucidated while evaluating the various parameters such as increment of nanoparticles, geometric-size and shape of solid particles etc. on pressure drop and pumping power. To conclude, this thesis will impart noteworthy role in designing and availing desired heat transfer and pressure drop requirements in heat transfer devices.
