Abstract null null Spout deflection has been widely encountered in spout fluidized beds and can seriously narrow the operating range of normal spouting. However, the underlying mechanism of spout deflection phenomenon remains unknown. In this study, two hypotheses are proposed to explain the spout deflection mechanisms in spout fluidized beds, and two virtual experiments are designed to verify these two hypotheses respectively using the Computational Fluid Dynamics-Discrete Element Method (CFD-D...

Abstract null null This paper presents a numerical study of the influence of burden profile on gas-solid distribution in a COREX shaft furnace through CFD-DEM model. The model takes into account the transient features of gas and particle flow under evaluation of five burden profiles, and the results show that the burden profile has a minor effect on the burden descending velocity. Caused by the segregation, the overall maximum and minimum porosities in the packed bed are observed in the case of ...

Abstract null null Ribbon mixers are used in various industries for the mixing of particle matter. The discrete element method (DEM) is used to investigate the effects of the particle size and density on particle mixing in a laboratory-scale ribbon mixer. The mixer consists of a ribbon impeller with spokes and a horizontal cylindrical vessel. The particle size varies from 5 to 15 mm, and density from 417 to 2500 kg/m3. A particle-scale index is used to analyse the mixing state, and the impeller ...

Abstract null null Gas-fine flow in a packed bed with lateral injection is numerically studied to understand the distribution and clogging behaviors of fine particles. A variety of variables (e.g., diameter ratio, the mass flux of fine particles, and rolling frictional coefficient) are investigated. The results show that with the decrease of diameter ratio, the cluster in the packed bed decreases and the dispersed fine particles increase. The number and size of cluster increase significantly as ...

Abstract null null Hydrogen, as a carbon-free fuel and reducing agent, has the potential to mitigate carbon dioxide emission in BF ironmaking and the shaft injection is one of the promising and feasible processes; however, its effects on non-renewable fossil fuels saving in ironmaking process and the in-furnace phenomena are still not clear. In this study, a multi-fluid BF model is adopted to study hydrogen shaft injection's influence on in-furnace phenomena and BF performance, including flow-th...

Abstract null null Hydrogen can be injected into blast furnaces (BFs) via tuyeres and fully replace pulverised coal injection (PCI) for lowering carbon emission, but hydrogen combustion in the raceway may affect raceway shape and size considerably. In this study, a three-dimensional (3D) transient CFD model is used for describing the complicated multiphase flow and thermochemical behaviours related to hydrogen combustion in the raceway of BFs, including the combustion of hydrogen and coke and dy...

Abstract null null In this study, a CFD-DEM reacting model featuring thermochemical sub-models is developed for describing gas–solid reacting flow related to raceway dynamics and coke combustion in an ironmaking blast furnace (BF). The simulation results show that a ring-type zone is formed around the cavity where the coke combustion and gasification occur with a large amount of heat released, leading to intense momentum and thermochemical exchanges in this zone. Heat fluxes contributed from rad...

Abstract null null The asymmetric ceramic microfiltration (MF) membrane is widely used in water treatment processes, yet the dependence of its intrinsic permeability on the microstructure parameters of different layers are not thoroughly understood. In this study, a numerical model combining the Discrete Element Method (DEM) with Lattice Boltzmann Method (LBM) is developed to simulate the fluid flow through the detailed pore structure of an asymmetric ceramic MF membrane. The model is validated ...

Abstract null null In this work, a recent smoothed CFD-DEM model is employed to study the segregation and mixing behaviours in a bi-disperse solid–liquid fluidised bed (SLFB) with different superficial liquid velocities and wide size ratios. Here, the poly-disperse drag model is applied, and its validity and advantage are confirmed. Besides, the qualitative and quantitative characteristics are systematically studied using a variety of indices, while the intermixing behaviour in the transition zo...
