Study of hybrid drag models for predicting hydrodynamic behaviour in a spouted bed

A hybridisation study of drag models was performed in a conical–cylindrical spouted bed by means of CFD simulations using an Eulerian–Eulerian multiphase model. In order to evaluate the simulation results, time‐averaged velocity distributions of the particulate phase were compared with the experimen...

Description
Summary:A hybridisation study of drag models was performed in a conical–cylindrical spouted bed by means of CFD simulations using an Eulerian–Eulerian multiphase model. In order to evaluate the simulation results, time‐averaged velocity distributions of the particulate phase were compared with the experimental data obtained by means of an optical fibre probe. The hybrid drag model considering both the volume fraction and the granular temperature distribution in the drag force calculation predicted the experimental data of the particle velocity distribution better than the other simulations performed in this work using other hybrid drag models.
