摘要:In this paper, we present a constitutive model to describe unsaturated flow that considers the hysteresis phenomena. This constitutive model provides simple mathematical expressions for both saturation and hydraulic conductivity curves, and a relationship between permeabilit...

摘要:The imbibition process into the pore structure of highly porous nanoparticle layers is investigated. The layers are fabricated with the Flame-Spray-Pyrolysis process and consist of aggregated \(\hbox {TiO}_{2}\) nanoparticles. Measurements of the pore structure reveal that these ...

摘要:The flow of polymer solutions in porous media is often described using Darcy’s law with an apparent viscosity capturing the observed thinning or thickening effects. While the macroscale form is well accepted, the fundamentals of the pore-scale mechanisms, their link with the...

摘要:This work presents the analytical solution and temporal moments of one-dimensional advection–diffusion model with variable coefficients. Two case studies along with the two different sets of boundary conditions are considered at the inlet and outlet of the domain. In the fir...

摘要:Coal is known as a dual-porosity media composed of cleat and matrix pore. Methane can be stored in the cleats or adsorbed on the inner surface of matrix pore. While fluid mobility is mainly controlled by the developed cleat network, methane desorption has a significant effec...

摘要:The subsurface spill of hydrocarbon fluids (from an underground leaking tank or from pipelines) is a widespread problem in the oil industry and hydrology. Under the assumption of low oil saturation, the migration of oil pollutant may be modeled by a nonlinear convection–diff...

摘要:Effect of local thermal non-equilibrium (LTNE) on onset of Brinkman–Bénard convection and on heat transport is investigated. Rigid–rigid and free–free, isothermal boundaries are considered for investigation. The assumption of LTNE leads to an ‘advanced onset’ situa...

摘要:The present study covers the problem of rotation of a porous disk under a viscous incompressible fluid that fills the half-space above the disk, which is the generalization of the von Karman’s problem. It is found that, instead of solving the exact problem, which is rather c...

摘要:The finite deformation of an unsaturated porous medium is analysed from first principles of mixture theory. An expression for Bishop’s effective stress is derived from (1) the deformation-dependent Brooks and Corey’s water retention curve and (2) the restrictions on the cons...

摘要:The permeability of the caved zone in a longwall operation impact many issues related to ventilation and methane control, as well as to interaction of gob gas ventholes with the mining environment. Insofar as the gob is typically inaccessible for performing direct measuremen...
