A Mathematical Model for Residence Time Distribution Analysis in Swirling Fluidized Bed

Knowledge of the complete history of the solid
particles in the case of a fluidized bed processes is
practically out of reach. In such cases the residence time
distribution becomes a very important design tool since all
particles that enter the system do not reside for the same
period of time. Residence Time Theory deals with the
estimation of the average time a particle remains in the
system and is necessarily probabilistic in nature. The
multi-parameter two-layer model was proposed in which it
consist of six independent parameters and one dependent
parameter. The effect of these parameters on the RTD
function, E(θ) are studied and the model is shown to be
highly versatile and capable of representing widely
different mixing conditions
