Nonlinear permeability

Ebook "Modelling water flow in unsaturated porous media: Accounting for nonlinear permeability and material heterogeneity" focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure.

Terzaghi’s 1D consolidation theory is commonly used for evaluation of consolidation characteristics of soft soils. Several simplifying assumptions have been made to resolve differential equation for one-dimension consolidation. This paper presents a generalized theory for onedimensional consolidation of soft soil with variable compressibility and permeability.

In this paper, we propose the solid-core photonic crystal fibers (PCFs) with hexagonal cladding infiltrated with propanol in the air-holes. The dispersion characteristics and zero- dispersion wavelengths of these PCFs have been compared with previous publications and analyzed in detail.
