A model for cluster size in risers

Particles in gas-solid flows aggregate to move as "clusters" and simultaneously develop gas "voids" free of particles. A model for gas-solid flow in risers considering the presence of clusters and voids is presented. Equations are developed to estimate the size of clusters consid...
