Thermo-Physical Properties of Al2O3 and Preparation Technique

Nanofluid is considered to the next invention of transfer of heat from the fluid which is providing and stimulating the possibility to increase heat transfer characteristics as compared to the base fluid of water. The experimental work of the paper in ethylene glycol (EG)-based Al2O3 nanofluid along with SDBS which acts as the surfactant was carried out. There are three various concentrations used as 0.1%, 0.15%, and 0.25%. The particle sizes show that the power on thermal conductivity variant along with volume concentration increases than the base fluid. The measured nanoparticles’ sizes are <50 nm. In addition, the fluid thermal conductivity is expected at isothermal process. From the observation, the nanofluid viscosity increases with changeable in the volume concentration. The thermal conductivity of the nanofluid also was improved while increase in volume concentration. The particle sizes show the power on thermal conductivity variant along with volume concentration
