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.

第二部分采用幾何分析法研究了二維和三維情況下的球形顆粒、立方體顆粒和板狀顆粒多孔介質(zhì)中流體流線的迂曲度一级黄啊啊啊啊网站，首先給出多孔介質(zhì)的理想幾何模型搜索黄色毛片片wwwwwwwww，通過分別考慮固體顆粒重疊時、不重疊時以及粒子的不同排列等情形時的流體流線在线免费性网站，然后對這些理想代表性流線的迂曲度取幾何平均和加權(quán)平均国产下药迷奸，最后推導(dǎo)出流體流過多孔介質(zhì)的迂曲度解析表達式。

Finally, weightedly averaging the existing evidences, the Dempster-sharer combination rule was used to realize information fusion.
