液滴布居平衡模型描述了液液萃取塔中溶质的液滴尺寸分布和质量分布。它考虑了液滴的相互作用(如破碎和合并)和柱体内的轴向输运，并将相入口视为点源。利用Galerkin方法对这两个积分-微分方程组进行离散。这导致了一个耦合的、非线性的、以双曲为主的守恒律系统，其中带有额外的液滴相互作用项。我们将守恒形式的对角隐式时空离散应用于这个偏微分方程组。
The drop population balance model describes the drop size distribution and the mass distribution of the solute in a liquid-liquid extraction column. It accounts for drop interactions (like breakage and coalescence) and the axial transport in the colunm, considering the phase inlets as point sources. Both integro-differential equations are discretized by utilizing Galerkin's method. This leads to a coupled, nonlinear, dominantly hyperbolic system of conservation laws with additional drop interaction terms. We apply a diagonally implicit space-time discretization in conservative form to this system of PDEs.
