Directional Permeability in Homogeneous Nonwoven Structures Part II: Permeability in Idealised Structures

The application of a newly derived model of directional permeability, presented in Part I of this series of papers, is described for a range of specific fibre-orientation profiles. A consideration of the permeability results predicted by both the new model and existing theoretical and empirical models indicates that it is of practical use and is generally applicable to fibrous media of either low or high porosity.
