Numerical simulation of the gas-solid two-phase flows in a precalciner

The gas-solid two-phase flows of the precalciner were simulated by different multiphase models, such as mixture model, the Eulerian model, including mixture and dispersed, and discrete phase model (DPM). The results of the different multiphase models were analyzed anti compared, showing the rationality of the diffiision and mixture of the cement raw meals and coal powder to some extent. Moreover, the results also shou; the rationality of the given inlets' parameters of actual process of the precalciner.
