In chapter 2, we focus on derivation of the tortuosity models for flow of Newtonian incompressible fluid in two- and three-dimensional porous media with spherical, cubic and plate-like particles by applying the geometrical method. We first present the ideal geometrical models of porous media to show the ideal and representative streamlines based on the assumption that some particles in porous media are unrestrictedly overlapped and hence of different configurations, then the average tortuosity is derived by geometrically and weightedly averaging these representative flow paths.

第二部分采用几何分析法研究了二维和三维情况下的球形颗粒、立方体颗粒和板状颗粒多孔介质中流体流线的迂曲度，首先给出多孔介质的理想几何模型，通过分别考虑固体颗粒重叠时、不重叠时以及粒子的不同排列等情形时的流体流线，然后对这些理想代表性流线的迂曲度取几何平均和加权平均，最后推导出流体流过多孔介质的迂曲度解析表达式。
