Keywords: nanofluid, thermal conductivity, molecular dynamics


The improvement of thermal conductivity by suspending nanoparticles in two hydrocarbon-based nanofluids is investigated by means of molecular dynamics simulations. Base fluids are methane and ethane and nanoparticles are pure copper. Two temperatures for which the experimental values for the thermal conductivity of the pure fluid exist are chosen. The Green-Kubo relation is utilized to calculate the thermal conductivity of colliodal systems. The effect of mass fraction of nanoparticles is investigated for each nanofluid and at each temperature.
