2009-10-30 Pulverised coal combustion was modelled using the commercial CFD code, FLUENT version 12. Turbulence was accounted for using the standard k-ε model, radiation using the discrete-ordinates model and the segregated pressure-velocity coupling scheme was used The chemistry occurring during coal combustion has been considered using a number of different approaches. During the validation case comparisons were made between the generalised finite rate model and the mixture fraction/PDF approach. Modelling
