INFLUENCE OF THE PRESENCE OF FINES ON THE FLUIDISATION OF LARGE PARTICLES
page 8
ABSTRACT
In this paper we investigated numerically the influence of the presence of fines on the fluidisation behaviour of large particles in a 2D fluidised bed. The presence of fines is found to increase the mixing of large particles within the bed due to collisions between groups of fines with the larger particles and due to a decrease in local porosity leading to stronger drag between the gas and solid phase.
