Storage Strategy in Granular Silos: Heat and Mass Transfer Analysis

This study delves into the investigation of heat and mass transfer within a vertical silo, specifically focusing on the dynamics of stationary two-dimensional forced or mixed convection within a cylinder entirely filled with a porous medium, represented by the granular product. The cylinder, maintained at a constant temperature T0, facilitates the transfer processes. The fluid flow is characterized by employing Darcy's model, while the chemical reaction aspect is incorporated through the Frank-Kamenetskii term. Notably, depending on the Reynolds number and Rayleigh number values, the findings unveil two distinct types of flow patterns: one marked by a chimney-type flow without recirculation, and another characterized by recirculation in the system. This delineation highlights the influence of key parameters on the flow dynamics within the studied vertical silo.
