This study summarizes the experimental results on the thermophysical and electrical properties of ethylene glycol based nanofluids containing carbon black nanoparticles. The specific surface area was found to have a significant influence on the fundamental properties of nanofluids developed with carbon nanoparticles, with the enhancement of electrical conductivity being one of the highest reported in the literature.
The paper summarizes results of experimental studies on thermophysical and electrical properties of ethylene glycol based nanofluids containing carbon black nanoparticles. Two types of nanoparticles differing in size and specific surface area were used to develop nanofluids. During the examination thermal conductivity, isobaric heat capacity, mass density, nanofluid-air surface tension, dynamic viscosity, refractive index and electrical conductivitywere measured in strict controlled temperature 298.15 K. Obtained results indicate that the specific surface area has great influence on these fundamental properties of nanofluids developed with carbon nanoparticles. Finally, the enhancement of electrical conductivity described in the paper is one of the highest reported for the nanofluids in available literature. (C) 2020 Elsevier B.V. All rights reserved.
