Brownian dynamics simulation to determine the effective thermal conductivity of nanofluids

摘要: A nanofluid is a fluid containing suspended solid particles, with sizes on the order of nanometers. Normally, nanofluids have higher thermal conductivities than their base fluids. Therefore, it interest to predict effective conductivity such under different conditions, especially since only limited experimental data are available. We developed technique compute using Brownian dynamics simulation, which has advantage being computationally less expensive molecular dynamics, and coupled that equilibrium Green–Kubo method. By comparing results our calculation available data, we show predicts good level accuracy.
