A New Approach of Synthesis of Al2O3 Nanofluid


Article Preview

The purpose of this paper is to research and develop a new nanofluid synthesis system that uses plasma arc as heat source to fabricate nanofluid having high suspension stability. This system uses high temperature produced by plasma arc system to cause transient vaporization to metal, which is then followed by the induction of vaporized metallic gas into the collection piping by the induction system. At the same time, it mixes thoroughly with the pre-condensed deionized water, and the mixture is then underwent a rapid cooling process. Because of low temperature, the metallic gas condenses into nanoparticles, which is finally stored in the collection tank in the form of nanofluid. This paper discusses the influence of working current towards the fabricated Al2O3 nanoparticle. Also, based on the Al2O3nanofluid having different pH values, it analyzes into the suspension stability of its Zeta potential value. Furthermore, it investigates into the absorption properties of Al2O3 nanofluid towards UV/Vis. Besides, as known from the experimental result of the fuel calorific test, when the weight concentration of the Al2O3 nanofluids that is produced by a better fabrication is 3%, it explores into its good combustion efficiency towards 92 unleaded gas.
