Introduciendo la dinámica de fluidos computacional en el análisis de flujos en medio poroso

This paper presents an introduction about how to model a flow through a porous medium with Computational Fluid Dynamics (CFD). To this end, a case study is proposed by simulating an air current produced by the fan of an air assisted sprayer through a porous medium (vegetation). The work is aimed at adjusting the porosity resistance to the air ow using experimental data.  The  adjustment  assesses  three  scenarios: one, considering only equal inertial losses between different porous bodies, two, considering both inertial losses  and  viscous  losses  and,  three,  considering  only  different  inertial  losses  between  different  porous bodies. Finally, velocities obtained in each simulation are compared with experimental data. The proposed methodology highlights the importance of employing suitable parameters when configuring CFD models.
