根据颗粒总数守恒的Ginzburg-Landau方程，建立了静电驱动颗粒介质中相分离和粗化的连续介质模型。在团簇发展较好的情况下，用连续介质模型推导出控制界面动力学的“尖锐界面”方程。该模型捕捉到了这个系统的基本物理原理。
A continuum model for the phase separation and coarsening in electrostatically driven granular media is formulated in terms of a Ginzburg-Landau equation subject to conservation of the total number of grains. In the regime of well-developed clusters, the continuum model is used to derive "sharp-interface" equations that govern the dynamics of the interphase boundary. The model captures the essential physics of this system.
