多孔介质中非均匀吸附时变流的传质
Mass transport subject to time-dependent flow with non-uniform sorption in porous media
摘要：
本文研究了多孔介质中溶质运移的捕获过程。从一个小尺度模型示踪粒子的轨迹，我们推导出相应的控制方程的流动相和固定相的浓度。我们表明，这种配方是相当普遍的，可以很容易地考虑到非常数系数，特别是空间依赖的吸附速率。输运方程的数值求解和Monte Carlo粒子跟踪模拟的空间污染物分布和突破曲线的比较，提出，以说明所获得的结果。
英文摘要：
We address the description of solutes flow with trapping processes in porous media. Starting from a small-scale model for tracer particles trajectories, we derive the corresponding governing equations for the concentration of the mobile and immobile phases. We show that this formulation is fairly general and can easily take into account non-constant coefficients and in particular space-dependent sorption rates. The transport equations are solved numerically and a comparison with Monte Carlo particle-tracking simulations of spatial contaminant profiles and breakthrough curves is proposed, so to illustrate the obtained results.
