包气带水气二相流国外研究综述

Review of Foreign Study on Two-Phase Flow in Vadose Zone

  • 摘要: 与传统的包气带中水流研究相比,水气二相流更准确地描述了包气带中的水与空气的流动情况,这对更好地了解固体废物处置场中污染物的运动规律具有重要的意义.与一相流明显不同的是,二相流考虑了空气的运动及其对水流的作用.根据国外近几十年来不同研究者的研究结果,总结了入渗过程中水的流动、空气对水流的影响及空气本身的压力变化情况,并分析了不同作者研究结果的差别.

     

    Abstract: In traditional study of water flow in vadose zone,little attention is paid to the effect of air entrapment,while this effect is rather important.There take place not only water flow,but also air flow in vadose zone.A better understand of two-phase flow is important to grasp the process of contaminant transport in vadose zone.This paper describes the water flow,air flow and its effect on water flow and the variation of air pressure during the infiltration based on the research in recent decades.The distinction among these results is also analyzed.
