In previous works a dissipative hydrodynamic model was used to simulate the behavior of a dense granular solid flowing through silos with simple geometries or with internal devices, showing good agreement with experimental results. That model has been upgraded taking into account the interaction between the solid itself and a nonreactive gaseous stream flowing countercurrent through it. This upgraded model has been compared with the results coming from an experimental campaign developed at Danieli R&D, and it will be shown that it still gives good agreement with the experimental results obtained.
