Experimental investigation of hybrid nanofluid on heat transfer and energy management

Abstract

In the recent years phase change materials PCM which are recommended as potential thermal energy storage media have been receiving significant attention The encapsulation technology of PCM is an effective way to enhance the thermal conductivity and solve the issues of leakage and corrosion during the melting process As a good choice of thermal energy storage materials the Nano Encapsulated Phase Change Materials NEPCM have many advantages such as small size large specific heat transfer surface and high heat transfer rate low temperature gradient during the processes Many literature reviews significantly disclose on the preparation characterization and application of nano encapsulated phase change materials This research work focuses on the enhancement of heat carrying capacity by the nano encapsulated paraffin wax of polyethylene alt maleic anhydride water mixture as one of the good phase change materials It is prepared in various least weight percentages of concentrations like 01 0 3 0 5 and 0 7 in the laboratory The Nano encapsulated paraffin wax of Polyethylene alt maleic anhydride water mixture utilizing the latent heat during melting and it can be used as a new hybrid nanofluid for various heat transfer applications The experimental investigations have been carried out on the preparation and evaluation of this hybrid nanofluid containing pluronic P 123 nano encapsulated paraffin wax of 50 to100 nm diameters in size newline
