| Description
| - Pro studium časoprostorových struktur reakčně-difuzně-konvekčních systémů byl použit model trubkového reaktoru s křížovým tokem, který je popsán dvěma parciálními diferenciálními rovnicemi, opatřenými okrajovými podmínkami podle Danckwertse nebo Neumanna. Analýze struktur předchází analýza stability a bifurkací stacionárního homogenního řešení, která je pak použita k predikci vzniku nehomogenních struktur. Existence těchto struktur je pak ověřována přímým numerickým výpočtem. Byly zkoumány např. Struktury typu pulsní a frontová vlna, tam a zpět se pohybující fronty (cik-cak struktury) a časoprostorový chaos. (cs)
- We study spatiotemporal solutions of reaction-diffusion-convection systems. As an example, we take a catalytic cross-flow tubular reactor with an exothermic chemical reaction of first order. Such a system is described by two partial differential equations, which can be solved together with boundary conditions. Neumann or Danckwerts boundary conditions are used depending on whether convection is involved or not. Analysis of spatiotemporal patterns, is preceded with analysis of stability and bifurcations of steady state in corresponding homogeneous system. Information from this analysis is then used to prediction of occurrence of different types of spatiotemporal patterns in reaction-diffusion and also reaction-diffusion-convection system. Spatiotemporal patterns are obtained by numerical integration. Effects of convection velocity on development of certain specific solutions are investigated, by using both numerical and analytical methods. Examples of simple spatiotemporal patterns are pulse and front
