边界层理论在裂隙水运移的研究进展

The Development of the Boundary Layer Theory in Solute Transport through Fracture Media

简要评述近几十年来,裂隙介质地下水运移过程中存在的问题,回顾了边界层理论的形成发展过程,重点评述了溶质非费克运移峰提前、拖尾和双峰现象。分析了边界层内部的流速分布,边界层厚度与非费克运移特征之间的联进一步指出今后研究方向,为裂隙介质地下水非费克溶质运移研究提供了新的思路和理论基础。

The issues of solute transport through fracture media and the development of the boundary layer theory were reviewed.A key point of the feature for non-Fickian transport was specially reviewed such as the features of early arrival of the peak value,long tailings and double peaks.The connection between the non-Fickian transport and the features of boundary layer such as the velocity distribution in the boundary layer and the thickness of the boundary layer was studied.The study can provide a new sight and theoretical foundation for non-Fickian transport in fracture media.
