7. Flow models

In the previous paragraphs, we focused on the overall operation of the CFL. However, local conditions such as solid retention in the ascending bed, and even the mapping of the presence of particles at any given point, are of vital importance. Indeed, the pressure balance alone, as described in paragraph 5.5 , is directly dependent on the mass of the solid present in the upper part of the bed (since the weight of the solid influences the pressure at...
