Abstract
Material properties are of great importance to pneumatic conveying. This paper presents a numerical study of the effect of particle friction coefficient on flow transition mode in horizontal pneumatic conveying in terms of the combined approach of computational fluid dynamics and discrete element method (CFD-DEM), facilitated with periodic boundary condition for solid and gas phases in the flow direction. The numerical results show that when gas velocity is varied, the change in particle friction coefficient leads to three typical flow transition modes, including Model I (dilute-phase only), Model II (smooth transition from dilute-phase, to unstable, finally to slug flow), and Model III (smooth transition from dilute-to dense-phase).
