Journal ArticleDOI
Validity of the permeability Carman-Kozeny equation: A volume averaging approach
Francisco J. Valdés-Parada,Francisco J. Valdés-Parada,J. Alberto Ochoa-Tapia,Jose Alvarez-Ramirez +3 more
TL;DR: The results indicate that simple empirical equations, commonly used in practice, are unable to describe the permeability functionalities over a broad range of porous media configurations.
Journal ArticleDOI
Mixing in confined stratified aquifers.
Diogo Bolster,Diogo Bolster,Francisco J. Valdés-Parada,Tanguy Leborgne,Marco Dentz,Jesús Carrera +5 more
TL;DR: This work uses a volume averaging approach to calculate the concentration distribution of an inert solute release at pre-asymptotic times in a stratified formation and finds an approximate, but accurate expression (when compared to numerical simulations) to evaluate mixing.
Journal ArticleDOI
Jump momentum boundary condition at a fluid-porous dividing surface: Derivation of the closure problem
TL;DR: In this article, a volume averaging method is used to derive a stress jump boundary condition that takes the form of a mixed stress tensor, which combines the global and Brinkman stresses at the dividing surface.
Journal ArticleDOI
Computation of Jump Coefficients for Momentum Transfer Between a Porous Medium and a Fluid Using a Closed Generalized Transfer Equation
Francisco J. Valdés-Parada,Francisco J. Valdés-Parada,Jose Alvarez-Ramirez,Benoit Goyeau,J. Alberto Ochoa-Tapia +4 more
TL;DR: In this paper, a closed generalized momentum transport equation (GTE) is presented, which is expressed in terms of position-dependent effective transport coefficients, which are computed from the solution of associated closure problems.
Journal ArticleDOI
On the effective viscosity for the Darcy-Brinkman equation
TL;DR: In this article, the effect of the slip boundary condition on the superficial average velocity is provided as a function of porosity, and it is shown that the average velocity tends to the one obtained by imposing non-slip conditions.
