Abstract We present numerical simulations of post-Darcy flow in thin porous medium: one consisting staggered arrangements circular cylinders and random distribution bounded between walls. The span a range Reynolds numbers, 40 to 4000, where the pressure drop varies nonlinearly with average velocity, covering nonlinear laminar fully turbulent regime. results are compared those obtained by replac...
The paper presents results of the modelling heat transfer at film boiling a liquid in porous medium on vertical heated wall. Such processes are observed cooling high-temperature surfaces pipes, microstructural radiators etc. Heating conditions wall were constant temperature or flux.
 An analytical solution was obtained for problem fluid flow and using model Darcy-Brinkman. It shown that le...
For the manufacturing of composite materials with textile reinforcement, the permeability of the textile is a key characteristic. Using the law of Darcy, permeability can be derived from a numerical simulation of the fluid flow, i.e. by solving the Navier-Stokes or Brinkman equations. In this report we present the results of simulations with two different flow solvers: a finite difference Navie...
This article analyses the convergence of the Vertex Approximate Gradient (VAG) scheme recently introduced in Eymard et al. 2012 for the discretization of multiphase Darcy flows on general polyhedral meshes. The convergence of the scheme to a weak solution is shown in the particular case of an incompressible immiscible two-phase Darcy flow model with capillary diffusion using a global pressure f...
