【摘要】：椭球形粒子作为一类重要的各向异性粒子,在生物、化工以及材料等领域有着广泛的应用。对椭球形粒子的扩散动力学进行深入地研究,不仅可以增进人们对各向异性粒子扩散动力学中基本科学问题的理解,而且可以为含各向异性粒子材料的设计与加工提供理论依据。因此,椭球形粒子的扩散问题一直是粒子扩散研究的焦点。虽然椭球形粒子扩散动力学的研究已经有一百多年的历史,其相关理论、实验和模拟研究工作很多,并取得了较大的进展,但是,系统的综述性文章相对较少。本文系统地总结了椭球形粒子扩散动力学的相关工作,包括:不同流体力学边界条件下椭球形粒子的扩散动力学和平动与转动扩散的耦合行为等。此外,本文还分析了椭球形粒子扩散动力学领域存在的关键科学问题,并对该领域研究方向进行了展望。
[Abstract]:As an important class of anisotropic particles, ellipsoidal particles are widely used in biological, chemical and material fields. The in-depth study of the diffusion dynamics of ellipsoidal particles can not only enhance the understanding of the basic scientific problems in the diffusion dynamics of anisotropic particles. It can also provide theoretical basis for the design and processing of materials containing anisotropic particles. Therefore, the problem of ellipsoid particle diffusion has always been the focus of particle diffusion. Although the research of ellipsoid particle diffusion dynamics has been more than one hundred years, there are a lot of theoretical, experimental and simulation studies, and great progress has been made. In this paper, the related work of ellipsoid particle diffusion dynamics is systematically summarized, including the coupling behavior of the diffusion dynamics of ellipsoid particles with rotational diffusion under different hydrodynamic boundary conditions. In addition, the key scientific problems in the field of ellipsoid particle diffusion dynamics are analyzed, and the research directions in this field are prospected.
