In this paper, a numerical scheme based on the immersed boundary method is used to study the motion of nano-sized particles subjected to Brownian motion and heat transfer. Our objective is to use this numerical technique as a tool to better understand the effect that Brownian forces have on the overall heat transfer process. The conventional approach to perform Brownian dynamic simulations is based on the use of a random force in the particle motion such that the fluctuation-dissipation theorem is satisfied. Our preliminary computational results suggest an increase in the thermal conductivity of the bulk fluid. Results are presented for several particles in a two-dimensional space.

In Figure 2 of the aforementioned paper by Alam, Clelland, and Hrenya, the stresses obtained using molecular-dynamic simulations of binary-sized systems were compared to stresses obtained using the kinetic-theory model for binary mixtures developed by Willits and Arnarson (Phys. Fluids, 11, p. 3116, 1999). An error was found in calculations for the Willits and Arnarson theory. Figure 1 (below) shows the corrected theoretical predictions, along with the original simulation data. These corrections result in an improved match between simulations and theory. In particular, the theoretical predictions compare well with the simulation data across the entire range of diameter ratios investigated.
