Developments and Future Insights of Using Nanofluids for Heat Transfer Enhancements in Geothermal Systems

Abstract

As we should encourage the uses of renewable sources of energy to make the world a better place and one of them is geothermal energy. It is the most suitable source of energy since it is possible to use it and generate sufficient power. There are various benefits to use geothermal energy among other renewable energy such as more availability factors, little maintenance, stable energy supply, and less pollution. And in order to continue to develop the technology, nanotechnology helps us to achieve that. From the literature reviews, we can say that nanofluids will play a crucial role in the advancement and the betterment of geothermal energy. The improvement relies on many factors together with the kind of nanofluid, concentration, and system specification. In keeping with the results of a study, the impact of mistreatment nanofluid on heat transfer rate became additional vital at higher flow rates. Nanofluids have a higher single-phase heat transfer coefficient, due to increased thermal conductivity. Thus nanofluids can be used to reduce the size of heat exchangers. And the effect is there will be a huge pressure drop.
