Experimental Study of the Comparison of Thermal Conductivity of Al2O3-Alpha Nanofluid with Lubricating Oil (160-HZ)

Discovery of Nanofluids leads to the revolution in Thermal conductivity process. Nanofluids are of small size basically 1 to 100 nm in size. This unique property of Nanofluids make it is a great property for Thermal Enhancement. Nanoparticles used in Nanofluids are made up of metals, oxides, carbides etc. Nanofluids are mixed with base fluid like lubricating oil, different Refrigerants, chemicals and water. In this present work  Alumina (Alpha) Nanofluids mixed with lubricating oil (160-HZ) at different Temperature range (30 to 70oC) with varying different volume concentration (0.1 to 5%) with 20 nm nanoparticles size to study the Thermal conductivity behavior. In short Alumina (Alpha) Nanofluids with base fluid lubricating oil (160-HZ) is prepared and then their Thermal conductivity is compared with base fluid i.e. Lubricating oil (160-HZ). Result shows that Alumina (Alpha) Nanofluids with base fluid lubricating oil (160-HZ) Shows superior Thermal conductivity as compared to Thermal conductivity of base fluid (160-HZ).
