OSTI ID:5221355
A numerical procedure is employed to examine the turbulent reactive flow field in an axial fired cylindrical combustor. Solution of the full 2-D elliptic partial differential equations is obtained with a second order closure model for turbulence. In addition, an eddy-breakup model is applied to characterize mixing controlled combustion. For the case of CO oxidation, predictions of species concentration distributions show good agreement with experiment. As such, the analysis is extended to treat the problem of pulverized coal combustion. This requires the addition of a devolatilization/diffusion controlled coal particle combustion in the model when rapid mixing (or eddy-breakup) occurs.
