Averaged Navier Stokes (RANS) approach was used to obtain a turbulent mean-field, employing the k-Epsilon turbulence model with two equations. The computational fluid dynamics software CFX 18.1 was utilized to solve the transport equations. Unstructured tetrahedral meshes generated by the ICEM CFD 18.1 software were employed in all models. The applied method proves to be suitable for reproducing the fluid dynamics of airflow in pneumatic systems of agricultural fertilizer spreaders, eliminating the need for physical prototypes.
