|Abstract:||The analytical characterization of thermophysical properties of metal oxide nanofluid has got significant attention in thermal industries due to their high capability of reducing energy loss and enhancing the efficiency of machinery parts. The fascinating heat transfer characteristics of green modulated iron oxide nanoparticles (IONPs) attain significant importance due to their wide range of diverse applications in different industries. In the current study, IONPs were successfully synthesized using an aqueous extract of Aloe vera (Aloe barbadensis) leaves to evaluate its effective thermophysical properties in base fluid like water. The average particle size of 11nm IONPs with its nanofluid of various volume concentrations 0.01 to 0.05 with a different temperature range of 30 °C to 50 °C shows an enhancement in thermal conductivity of 34.08% compared to distilled water (base fluid). Different characterization technique like Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transforms infrared (FTIR) spectroscopy, UV-visible spectroscopy, and particle size analyzer has been employed to get characteristic modification and formation of iron oxide nanoparticles. The experimentally measured values of thermal conductivity were compared with existing theoretical models for effective enhancement in thermophysical properties and the same was analyzed with the importance of green technique.|
