CFD-DEM modelling of raceway dynamics and coke combustion in an ironmaking blast furnace

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....
