reactors. Through these developments in reactor modeling, it is becoming evident that unless the influence of the complex hydrodynamics of fluidized bed reactors is accounted for, it is not possible to develop a comprehensive model which can be used for reactor engineering purposes. CFD models can provide information about such complex hydrodynamics of fluidized bed reactors. It may not be efficient to o a
