FLOW OF POLYMERIC LIQUIDS THROUGH POROUS MEDIA
-
摘要: 聚合物流体在多孔介质中渗流的研究是近年来有重大进展的领域。本文介绍从力学与物理方法进行渗流机理研究的思路、主要结果和当前活跃的研究课题。流体的非牛顿性对复杂边界条件下均匀流体力学效应的影响已得到了较好的定量处理;揭示了拉伸流粘弹特性对渗流影响的机理,其定量描述则尚有待努力。进而讨论了石油工程中十分重要的非均一流体渗流的新进展,包括大分子效应与粘性指进效应及其分形描述。对于上述物理效应的综合考虑将使聚合物渗流力学研究进入新的阶段。Abstract: Considerable progress has been achieved an the research on the flow of polymeric liquids through porous media in recent years. In this paper, main advances in this area are reviewed and the emphasis is put on the theoretical approaches on the mechanism and some recent active research branches of the flow of polymer solutions through porous media. It is pointed out that among the macro-effects on the homogeneous fluids with non-slipping boundary conditions, non-Newtonian (shearthinning) behavior has been qua...
