Clogging a Porous Medium
H. J. Seybold, Izael A. Lima, Ascânio D. Araújo
Flows through porous media can carry suspended and dissolved materials. These sediments may deposit inside the pore-space and alter its geometry. In turn, the changing pore structu…
Numerical Simulation of Particle Flow in a Sand Trap
A. D. Araújo, J. S. Andrade, L. P. Maia +1
Sand traps are used to measure Aeolian flux. Since they modify the surrounding wind velocity field their gauging represents an important challenge. We use numerical simulations und…
The distribution of local fluxes in porous media
Ascânio D. Araújo, Wagner B. Bastos, José S. Andrade +1
We study the distributions of channel openings, local fluxes, and velocities in a two-dimensional random medium of non-overlapping disks. We present theoretical arguments supported…
