The gas-particles flow in an interconnected bubbling fluidized cold model is
simulated using a commercial CFD package by Ansys. Conservation equations of
mass and momentum are solved using the Eulerian granular multiphase model.
Bubbles formation and their paths are analyzed to investigate the behaviour
of the bed at different gas velocities. Experimental tests, carried out by
the cold model, are compared with simulation runs to study the fluidization
quality and to estimate the circulation of solid particles in the bed.
