Modeling microgeometric structures of porous media with a predominant axisfor predicting diffusive flow in capillaries

This paper presents a method for modeling microgeometric structures of poro us media with a predominant using successive cross-sections. The proposed m odel takes into account the properties of diffusive flow in capillaries. In order to characterize uncertainty and imprecision occurring in geometric f eatures of cross-sections, we introduce the concept of connection degrees a s well as tracking degrees based on fuzzy theory. The proposed model can be used for classifying different types of media and finding the relationship between the geometric structure of a porous medium and its physical proper ties. This model has been successfully applied to polyester yam structure. (C) 2000 Elsevier Science Inc. All rights reserved.
