Eulerian-Lagrangian simulation of a bubbling fluidized bed reactor: Assessment of drag force correlations

Ku Xiao-Ke, Li Tian, Lovas Terese

An Eulerian-Lagrangian approach is developed within the OpenFOAM framework to investigate the effects of three well-known inter-phase drag force correlations on the fluidization behavior in a bubbling fluidized bed reactor. The results show a strong dependency on the restitution coefficient and the friction coefficient and no occurrence of bubbling and slugging for the ideal-collision case. The mean pressure drops predicted by the three models agree quite well with each other.
