Abstract
Ferrofluid is colloidal system poised of single domain of nanoparticles dispersed in a carrier liquid. Ferrofluid bargain incredible new potentials to improve heat transfer performance compared with pure liquids and can be watchful to be the next-generation of heat transfer fluids. In the present work Fe3O4 nanoparticles were synthesized by co-precipitation chemical synthesis, and were coated with oleic acid as surfactant agent. Owing to their excellent characteristics, ferrofluid find varied applications in enhancing heat transfer. Research work on the concept, heat transfer enhancement mechanism, and application of the ferrofluid is still in its primary stage. This study affords an investigation in this field with focus on applications of ferrofluid due to their thermophysical and electrical properties.
