Nanofluids, engineered suspensions of nanosized non-organic particles in base fluids have shown some interesting thermo-physical properties and heat transfer augmentation in various cooling systems. A gigantic number of research works is documented so far, and it is going on to explore various aspects of nanofluids such as their formulation, physical properties, and their utility in various engineering applications. Various investigations report that this class of fluid shows remarkable enhancement in various thermophysical properties such as thermal conductivity, viscosity, heat capacity, density, and surface tension. Enhancement in convective heat flow, critical heat flux enhancement (CHF) enable them as a special class of coolant for high-temperature applications including automobile, micro-electromechanical systems (MEMS), defense and power sectors. To explore the significance of such investigations, the application of nanofluids as coolants in fusion reactors is a very good aspect of this technology. Research agencies around the globe have already initiated research works to explore the potential of nanofluids in fusion reactors. The present contribution revises the theoretical and experimental studies reported on nanofluids, and their potential as future generation coolant for fusion reactors is featured presenting the current status of research. |
