| Nanofluids as a quite new group of nanomaterials are very promising. A great potential of nanofluids was noted in second half of twentieth century and it was related with high increase of thermal conductivity. The most favourable effects of using nanofluids can be achieved in heat transfer systems, but also in other branch of industry like car, energy, and mining industry, even biomedicine industry. This paper presents results of experimental investigation of electrical conductivity of nanosuspension containing indium oxide nanoparticles dispersed in ethylene glycol. Five samples with volume fraction in the range 0.0016-0.0081 were prepared using two-step method. After preparation, all samples were impatiently investigated in controlled temperatures in the range from 298.15 K to 333.15 K. Measurement were conducted using conductivity meter MultiLine 3630 working with conductivity probe LR925/01 (WTW GmbH, Weilheim, Germany). Obtained results indicate that changes in volume concentration and temperature have strong impact on electrical conductivity of In2O3-EG nanofluids. |
