A computational approach has been developed for the prediction of gas–particle flow and the simulation of the classification-settling characteristics of a particulate material flow in a gravitational classification chamber (GCC). By taking into account the classification chamber geometry and operating parameters, as well as the particulate material physical properties, the developed computational code allows the simulation, improvement and control of the operational characteristics of industrial settling, classification and/or separation chambers commonly used in process industries. The work assesses the performance of the computational code and demonstrates the capability of dedicated computational tools to model with accuracy complex industrial multiphase flows in order to support design criteria.
