SINOPSIS

A new advanced subgrid scale (SGS) model for coal particle combustion and gasification was developed. The new model considers a detailed representation of the diffusion and convection phenomena in the direct proximity of the coal particle, which are generally neglected by standard models available in literature. This paper shows the coupling of the new model with the commercial CFD code Ansys-Fluent and its validation considering a full-scale furnace. In particular the IFRF pulverized coal MILD combustion experiments are considered for validating the results of the new model, showing a better agreement with experiments with respect to a standard model.
