An Investigation on Using Nanofluids(Al2O3) in Heat Exchangers Efficiency through Simulation Environment of FLUENT

A Heat exchanger is an application which affecting the operation used to exchange the heat from flowing of one liquid on one side of a barrier horizon to another liquid on the other side of a barrier horizon. Resilient heat exchangers have two streaming fluent at diverse temperatures that are desperate for a solid shell. In the recent scenario, the shell and tube heat exchanger (STHE) is the utmost flexible and appropriate for high-pressure operations, independent of pressure and temperature utilized in power production commercial enterprises, air conditioning and refrigeration, space, auxiliary large chemical development and other expansive chemical processes. Nanofluids have more heat transfer rate than conventional fluids. Nanofluid is most convenient for quick heating and cooling applications. Heat transfer increases due to low specific heat and high density, high-temperature distribution and large surface volume of nanoparticles in the base fluent. In this paper we investigate on some changes of different parameters of heat transfer by using nanofluid (Al2O3) through the simulation environment of FLUENT, also it has to be mentioned that our designing structure had been created by using Gambit.
