In this paper, new findings on ratio of thermal conductivities and electrical conductivities of nanofluids inwater: ethylene glycol (EG) mixtures are established. Thermal conductivities and electrical conductivities of base fluids which are water: EG mixtures with concentration ranging from 0 % ethylene glycol up to 100 % ethylene glycol were measured.

Electrical conductivities measured in 0.1, 0.3 and 0.5 % volume concentration of Al2O3 in base fluid also observed to decrease as the EG concentration increased even though the base fluids’ electrical conductivity behave differently. Thermo-electrical conductivity ratio (TEC) has also been established based on both thermal and electrical conductivity findings.
