Abstract: The paper proposes a modified Maxwell formula applied to the calculation of the thermal conductivity of nanofluids. It is shown that the use of elongated particles or chains of nanoparticles leads to a significant increase in thermal conductivity. Theoretical estimates based on the proposed model are in good agreement with experimental data.

Keywords: Thermal conductivity, nanofluids, elongated particles, chains of nanoparticles, Maxwell formula.
