Abstract:
The main goal of this work is the theoretical prediction and qualitative analysis of the nonlinear behavior of fluidized bed granulation with external classification. First a new population balance model including a mass balance of the fluidized bed unit has been developed. Using methods from nonlinear systems analysis, such as a numerical bifurcation and stability analysis, unstable regions in the parameter space have been predicted. Due to the simplicity of the model the presented results are only qualitative. Future research will concentrate more on a quantitative investigation of the nonlinear process behavior with more detailed models and experimental validation.
