A simulation of the behavior of bulk solids continuously flowing through a silo with internal flow feeders has been performed by means of a dissipative hydrodynamic model.

The results obtained by these calculations and those found experimentally agree, not only with regard to the velocity profiles, but also relative to the pressure on the silo walls. The dissipative hydrodynamic model represents the behavior of granular solids, not only with respect to the velocity and descent profiles of the material, but also with respect to the stresses at these walls.
