COMPARATIVE STUDY OF VARIOUS THERMO - PHYSICAL PROPERTIES OF METALLIC & OXIDES NANOFLUIDS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 7
Abstract
Development of Energy efficient fluids for various heating or cooling systems is one of the major reqirement for vigorously growing technology. Suspension of nano sized (usually 0 - 100 nm) particles into base fluids is termed as Nanofluid, a new trend of heat transfer fluids for various thermal applications. Due to enhanced thermal conductivity over conventional fluids, they became panacea for heat transfer applications. Since the metals have high thermal conductivity a s compared to metal oxides, the metallic nanofluids shows superior thermal performance comparatively. In present work, Nanofluids of 0.1%(Vol.) concentration were prepared using Aluminium Oxide nanoparticles and Aluminium nanoparticles in double distilled water. Various thermo physical properties of these two nanofluids was measured at different temperature values. It was shown that the thermal conductivity of Al/water is around 47 % higher than Al2O3/water nanofluids at temperature around 60°C which make s Al/water nanofluids more feasible for high energy density applications.
