A recent examination on the nano coating techniques in heat transfer applications

Abstract As per the survey of the World Energy monitor issue 2019 portrait that since 1975, there was a rapid growth in the energy demand around the world till now and it is mainly satisfied by fossil fuels and centralized power generation. In the future, there should be varied energy transition need to happen to decrease the usage of fossil fuel. In this regard, much research work had been going on to ensure proper energy consumption without wasting much energy. Nowadays research on coating techniques was evolved to control the waste heat emission and to reduce corrosion reduction in pipes to conserve the most energy-releasing as an unused. In that, the usage of nanoparticles as a coating material in the area of heat transfer applications were evolved to enhance its working capacity. This review paper depicts the results obtained by various researchers with the usage of nanoparticles as coating materials over the other materials to enhance the thermal and corrosion properties by exploring with diverse nanoparticle size, coating thickness, morphological characteristic detecting instruments and usage of nanoparticles in diverse applications were studied. This paper may give the researchers a basic idea to pick the valid coating materials with their properties and applications for their study in heat transfer equipment.
