Prediction of wear and its effect on the multiphase flow and separation performance of dense medium cyclone

A CFD-DEM approach, coupled with the Finnie wear model, has been developed to predict the wear rate of a DMC under various operational, material and geometrical conditions. The figure above shows the predicted wear rate at the DMC walls for different coal types: (a), coking coal (particle size is 25 mm); (b), thermal coal (particle size is 25 mm); and (c), thermal coal (particle size is 0.25 mm).
