TY - JOUR TI - Numerical simulation of gas-solid flow in an interconnected fluidized bed AU - Canneto Giuseppe AU - Freda Cesare AU - Braccio Giacobbe JN - Thermal Science PY - 2015 VL - 19 IS - 1 SP - 317 EP - 328 PT - Article AB - 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.
