DPM model segregation validation and scaling effect in a rotary drum

Abstract Discrete phase method (DPM) model was used to analyse rotary drum systems for segregation behavior. DPM simulations were performed comparison with a dynamic experimental measurement from the literature. This included and time-averaged particle velocity field, which validated data. In addition, direct parcel scaled simulation study effect of size scaling. The dynamics evaluated using Lacey mixing index. work shows decreases increasing while keeping same size. It further that given deviate after certain scaling limit. limit also increases
