A model has been developed to investigate the detailed thermal-hydraulic mixing phenomena in an atmospheric fluidized bed combustor. The model is three-dimensional and transient. The solution of the conservation equations for mass, momentum, and energy as a boundary value problem in space and an initial value problem in time are embodied in the COMMIX computer code. The model has been applied to investigate several different over-fire air port configurations to assess the impact of the thermal mixing processes. The results show the usefulness of such analysis to design considerations. 8 refs., 17 figs.
