“…The thermal properties of a distilled water-based MWCNT+Y2O3 combination with a 20:80 weight ratio were experimentally investigated. The results demonstrate that the thermal conductivity coefficient increases with both temperature and concentration, especially at high concentrations and high temperatures [20]. Lee et al [21] studied the thermal conductivities and viscosities of aqueous nanofluids containing Al2O3 nanoparticles in the range of 0.01-0.3 vol.% and reported that the viscosity of the nanofluids decreased significantly with temperature and increased nonlinearly with the particle concentration.…”

Thermal conductivity and viscosity of CuO/ethylene glycol/water, multiwalled carbon nanotubes (MWCNT)/ethylene glycol/water and CuO/MWCNT/ethylene glycol/water nanofluid systems were determined experimentally at a temperature range of 5 to 50 °C and very low concentration (less than 0.008 vol.%). The obtained results show that the thermal conductivity of nanofluids significantly increases with increasing nanofluid temperature. It is also verified that the enhancement in thermal conductivity of nanofluid systems containing mixed CuO/MWCNT is more than systems containing CuO or MWCNT individually. Analyses of the viscosity data indicate that the viscosity diminishes with increasing temperature. The higher concentrations of all nanofluid systems possess higher viscosity. The results also show that the viscosity of nanofluid systems containing mixed CuO/MWCNT is between the viscosities of the systems containing CuO and MWCNT individually.
