摘要 有机污染物 ( NAPLs)在地下水非饱和区和饱和区中的运动属于多孔介质中的多相流问题 ,其中毛细压力与饱和度的关系是求解多相流运动方程的基础。前人的研究表明 ,对于一定的多孔介质 ,建立其中任意两相流的统一毛细压力饱和度关系曲线是可能的。利用多孔介质毛细管模型 ,得到了利用气水两相的毛细压力饱和度关系式推求气 -NAPL、水 -NAPL两相的毛细压力饱和度关系的毛细压力折算系数。从而得出对于同一介质中的任意两相流动 ,只要某两相的毛细压力饱和度关系 (一般选择气水两相 )已知 。 The movement of Non aqueous Phase Liquids (NAPLs)(usually organic compounds) in subsurface porous media is a problem of multiphase flow. Prior to solving governing equations of multiphase flow, the capillary pressure saturation relationships of different multiphase must be set up. Based on previous research, it is understood that for any porous media it is possible to get an unified capillary pressure saturation relationship for arbitrary two phase flow, and the problem is how to estimate the scaling coefficients of capillary pressure. Using capillary rube model of porous media,scaling coefficients of capillary pressure are deduced in this paper. The results show that the scaling coefficients, in the same porous medium, if any pair of two phase (usually air water two phase system is selected as the reference) capillary saturation relationship is known, then the other two phase (air NAPL and NAPL water) capillary saturation relationships can be obtained too.
