Abstract The intrinsic permeability is a crucial parameter to characterise and quantify fluid flow through porous media. However, this typically uncertain, even if the geometry of pore structure available. In paper, we perform comparative study experimental, semi-analytical numerical methods calculate regular structure. particular, use Kozeny–Carman relation, different homogenisation approaches (3D, 2D, very thin media pseudo 2D/3D), pore-scale simulations (lattice Boltzmann method, Smoothed...
Abstract The correct choice of interface conditions and effective parameters for coupled macroscale free-flow porous-medium models is crucial a complete mathematical description the problem under consideration accurate numerical simulation applications. We consider single-fluid-phase systems described by Stokes–Darcy model. Different sets coupling this model are available. However, these often arbitrary. use large-scale lattice Boltzmann simulations to validate comparison against pore-scale...

Abstract Physically consistent coupling conditions at the fluid–porous interface with correctly determined effective parameters are necessary for accurate modeling and simulation of various applications. To describe single-fluid-phase flows in coupled free-flow porous-medium systems, Stokes/Darcy equations typically used together conservation mass across interface, balance normal forces Beavers–Joseph condition on tangential velocity. The latter is suitable parallel to but not applicable...
Abstract Existing model validation studies in geoscience often disregard or partly account for uncertainties observations, choices, and input parameters. In this work, we develop a statistical framework that incorporates probabilistic modeling technique using fully Bayesian approach to perform quantitative uncertainty-aware validation. A perspective on task yields an optimal bias-variance trade-off against the reference data. It provides integrative metric parameter conceptual uncertainty....
Fluid flows in coupled systems consisting of a free-flow region and the adjacent porous medium appear variety environmental settings industrial applications. In many applications, fluid flow is non-parallel to fluid–porous interface that requires generalisation Beavers–Joseph coupling condition typically used for Stokes–Darcy problem. Generalised conditions valid arbitrary directions are recently derived using theory homogenisation boundary layers. The aim this work mathematical analysis...
Boundary conditions at the interface between free-flow region and adjacent porous medium is a key issue for physically consistent modeling accurate numerical simulation of flow transport processes in coupled systems due to driven nature such processes. Interface available literature have several weak points: most them are suitable only flows parallel fluid-porous interface, some restricted specific boundary value problems, others contain unknown model parameters which still need be...
