In the present paper, we study the self-diffusion of aggregating magnetic particles in bidisperse ferrofluids. We employ density functional theory (DFT) and coarse-grained molecular dynamics (MD) simulations to investigate the impact of granulometric composition of the system on the cluster self-diffusion. We find that the presence of small particles leads to the overall increase of the self-diffusion rate of clusters due the change in cluster size and composition.
在本文中,我们研究了双分散铁磁流体中聚集磁性颗粒的自扩散。我们采用密度泛函理论(DFT)和粗粒化分子动力学(MD)模拟来研究系统粒度组成对团簇自扩散的影响。我们发现,由于团簇尺寸和组成的变化,小颗粒的存在导致团簇自扩散速率总体增加。
