A Review on the Enhancement of Heat Exchanging Process Using TiO_2 Nanofluids

摘要

Because of the decrement of fossil fuels, the energy industries are pushed to consume lesser rate to produce the power with the higher demand, as per the world energy outlook report 2018, the demand for natural gas, coal for power plants and fuel for automobiles increases 1.6% per year upto 2040 and 23 million barrels per day, respectively. Thus, this issue has to be resolved only by optimizing the energy transformation which is achieved by the optimum utilization and enhancement in the performance of the heat exchanging devices since heat exchanging process is very much significant in many industrial applications. Many types of research are undergoing for many years to find a technique with unceasing heat transfer rate. This is insignificantly achieved with the introduction of the nano-sized particles mixed with the base fluid which is having anomalous thermal behavior. In this review paper, the complete investigation on the utilization of TiO_2 nanofluid with its thermal properties and volume concentration over the various base fluids in addition to the influence over the Reynolds and Nusselt number during heat exchanging process has been discussed.
