Abstract: The influence of temperature and volume fraction on the thermal conductivity and viscosity of nanofluid produced from Terminalia Superba (Afara - EG) were investigated. An average particle size of 100nm was dispersed into pure ethylene glycol and magnetically stirred for 10 minutes for proper distribution and absorption before sonication. Volume fractions of 0.2%, 0.4%, 0.6%, 0.8% and 1.0% were produced by ultrasonication for an optimum sonication time of 30 minutes with amplitude of sonication as 80hz. Results of the thermophysical properties of Terminalia Superba tree bark nanofluid using ethylene glycol as base fluid are presented. As the temperature elevated from 20oC to 70oC, the viscosity decline. A rise in viscosity was recorded as volume fraction increased from 0.2% to 1.0%. The thermal conductivity increased with increase in temperature and volume fraction. Predicted values of thermal conductivity and viscosity for nanofluid produced from Terminalia Superba were found to be higher than the experimental values. Due to its low viscosity and thermal enhancement, it is suitable for application in cooling of electronics.
