Modeling of hydrodynamics of highly concentrated granulated media in the blending silo

In this paper we study the dynamics of highly concentrated granulated well granular medium in the vertical mixing hopper. To describe such a flow, a differential model proposed by the authors based on the provision of continuum mechanics with allowance for rheological properties of the granular material and the additional transport equation for the chaotic energy of the pulsation of the granules. The reliability of the proposed model is established by comparing the calculated average velocity distribution environment with the experimental data.
