Estimation of Dynamic Viscosity for Cobalt Oxide/Glycol Nano Fluid

In this study the effects due to temperature and shear rate on viscosity for Co3O4/glycol based Nano fluids at different concentration of metal oxide and different temperatures were experimentally investigated. The structure of the prepared Co3O4/glycol nanoparticles was confirmed using XRD (X-Ray Diffraction) technique. All viscosity measurements were conducted using a capillary viscometer, the viscosity experiment were carried out at wide temperatures ranging between 20°C and 80°C to determine their applicability in such range. The viscosity data were collected using a programmable rhemoter. The result showed that the Co3O4 glycol exhibit increasing viscosity with increasing nanoparticle loading and decreasing viscosity with increasing temperature.
