Transversal moving-front patterns: Criteria and simulations for two-bed and cylindrical shell packed-bed reactors

Bifurcation diagram showing domains of transversal patterns is constructed using a learning two-bed model. These predictions are verified by direct numerical simulations of the continuous 2-D cylindrical shell model showing various types of moving transversal patterns within a feasible domain of the state parameters with PeC>PeT. In the case of varying ratio (κC≠κT) the pattern domain can be significantly extended toward larger PeC/PeT.
