The effective thermal conductivity of a nanofluid was computed using Brownian dynamics simulation. Nanofluids contained suspended solid particles with sizes on the order of nanometers and had higher thermal conductivities than their base fluids. The Brownian dynamics simulation was computationally less expensive than molecular dynamics and was coupled with the equilibrium Green-Kubo method for the investigation. It was found that by the Brownian dynamics simulation the particle velocity, position and energy at each step were obtained.
