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。 Compared with the traditional study of water flow in the aeration zone, the two-phase flow of water-gas can describe the flow of water and air in the aeration zone more accurately, which is helpful to better understand the movement rule of the pollutants in the solid waste disposal site It is of great significance. In distinct contrast to a phase flow, two-phase flow takes into account the movement of the air and its effect on the flow of water. According to the results of different researchers in recent decades, this paper summarizes the inflow of water, the influence of air on water flow and the pressure of air itself, and analyzes the differences between different authors.
