Název v původním jazyce

Pattern formation and chaotic dynamics in a cross-flow catalytic converter with kinetics of detoxification of exhaust gases

Popis výsledku v původním jazyce

Heterogeneous catalytic reactions and catalytic reactors are known to exhibit complex dynamic behaviour. In the past three decades, significant progress in understanding this complexity has been made using the tools of nonlinear dynamics and advanced experimental methods. Nonetheless, theoretical predictions of pattern occurrence in various types of reactors including the fixed bed and cross-flow catalytic reactors are of great interest in understanding feasible dynamics in reactors used in applications. In this contribution, the range of patterns occurring due to interaction of transport and reactions characteristic of the three-way catalytic converter (TWC) have been explored. We examined whether and how spatiotemporal structures such as spatially nonhomogeneous steady states and travelling waves are produced. Furthermore we found that the system displays a wide variety of chaotic spatiotemporal patterns, which were examined in detail.
