摘要：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.
