EXPERIMENTATION AND ANALYSIS OF THE HEAT TRANSFER BEHAVIOUR OF THE HYBRID NANOFLUID (Al2O3 + ZnO) IN A PARALLEL FLOW HEAT EXCHANGER

Abstract

Estimating the heat transfer enhancement for various Reynolds numbers in turbulent ranges at a volume concentration of 0.1% is the goal of the current investigation. Compared to conventional heat transfer fluids, nanofluids are thought to be new-generation fluids with superior heat transfer properties. There is a lot of promise for heat transfer applications with the nanofluid, a new field of study. Thermophysical characteristics of ZnO and Al2O3 at varying volume concentrations have been experimentally evaluated using a mixture of water & Mono Ethylene Glycol as the basis fluid. The thermo-physical properties of the combination are greatly enhanced when metal oxide hybrid nanoparticles are suspended in the base fluid. The outcomes of studies on a hybridized nanofluid mixture (Al2O3.ZnO) show exceptional thermophysical characteristics. As a result, we can specify a 60:40 Al2O3.Zno mixture that yields promising outcomes in both an economical and experimental manner. Al2O3.ZnO will have numerous opportunities to improve their performance through small-scale industrial applications. Compact heat exchanger design and high-energy device miniaturization are only feasible with fluids that perform better in heat transfer.
