CHOOSING STRUCTURE-DEPENDENT DRAG COEFFICIENT IN MODELING GAS-SOLID TWO-PHASE FLOW

Introduction Gas-solid two-phase flow is often encountered inchemical reactors for the process industry. For industrialusers, design, scale-up, control and optimization for thesereactors require a good understanding of the hydrody-namics of gas-solid two-phase flow. For researchers, ex-ploration and prediction of the complex phenomena call fora good comprehension of the heterogeneous structure andof the dominant mechanisms of gas-solid and solid-solidinteractions.
