In bulk warehouses, the conservation of grains for a certain period of time depends mainly on an efficient aeration system, preserving the quantity and quality of the stored grains.To simulate an aeration system, a mathematical model and software were developed to simulate the 3D airflow distribution in horizontal bulk warehouses, under inhomogeneous and anisotropic conditions.The formulated air flow problem was solved using the Finite Element Method, with geometries and tetrahedral meshes of real grain storage systems.With the simulation it was possible to analyze the distribution of air flow at all points of the stored grain mass.To evaluate the effectiveness of air distribution, the local specific flow criterion was used.
