We discuss the Brownian dynamics of colloids in confinement with special emphasis on the influence of the solvent dynamics. We review the derivation of a dynamic density functional theory (DDFT) including some aspects of hydrodynamic interactions and its application to the micro-rheology of suspensions. In particular we discuss the failure of Stokes' law in suspensions and non-equilibrium solvent structure mediated interactions. With regard to hydrodynamic chromatography we also discuss the stationary transport of particles in narrow channels, and the reasons for the failure of DDFT in this situation.
我们讨论了受限胶体的布朗动力学，特别强调了溶剂动力学的影响。我们回顾了动态密度泛函理论（DDFT）的推导，包括一些流体力学相互作用的方面及其在悬浮液微流变学中的应用。特别是，我们讨论了悬浮液中斯托克斯定律的失效以及非平衡溶剂结构介导的相互作用。关于流体力学色谱法，我们还讨论了在狭窄通道中颗粒的稳态传输，以及 DDFT 在这种情况下失效的原因。
