General computer models are being developed to provide a theoretical description of gas-solids flows in reactors for coal gasification. These models include representations of fluidized and entrained systems. During this twelve month effort the theoretical formulation of the thermohydrodynamics and chemistry for the fluidized bed flows was developed and incorporated into finite difference computer codes. Calculations, with the thermohydrodynamic code, of nonreactive flows in fluidized beds, were compared with experimental measurements and good qualitative and quantitative agreement was demonstrated. The chemistry code was used to model a homogeneous, constant temperature, steady flow gasifier (CO/sub 2/ acceptor process) and good quantitative agreement was obtained between the calculation and pilot plant data. The combination of the thermohydrodynamics and chemistry to provide a model for reactive flows is briefly discussed.
