## ANALYTICAL MODELING OF SPHERE SYMMETRY DISPERSION IN MICRO-AGGREGATES POROUS MEDIA

• 摘要: 本文研究球对称弥散问题,模型中考虑了孔隙介质的微结构特征。这种微结构起着广义的吸附作用,在溶质的输运过程中有滞后效应。文中考虑了五种微结构模型,它们是均衡吸附模型,一阶线性动力吸附模型、板状、柱状和球粒结构模型。分别求得Laplace空间的解析解,用Stehfest的数值反演技术获得各种模型的溶质浓度分布,并对有关的影响因素进行了量值考查,对认识微结构模型的特性有帮助,可以作为地层排污、特殊条件下的石油开采及溶滤萃矿等工程设计的理论依据。

Abstract: This paper studies sphere symmetry dispersion problem. In the mathematical model the micro-aggregates of porous media are considered. The micro-aggregate plays a role of general adsorption, and in transportation process of solute it results in retardation of concentration wave. In this paper five kinds of micro-aggregates are concerned, i.e. local equilibrium sorption model, first-order rate-limited sorption model, parallel layer diffusion model, cylindrical diffusion model and spherical diffusion model.
