Parametric analysis of the models of a stirred tank reactor and a tube reactor

A parametric analysis is performed for a basic model of the combustion theory with dimensional parameters. The model describes the dynamics of a first-order exothermic reaction in a well-stirred tank reactor. Parametric dependences of steady states on dimensional parameters, curves of multiplicity and neutrality of steady states, and parametric and phase portraits of the system are constructed. Regions of multiple steady states and self-excited oscillations and a region of technological safety are distinguished. Combustion regimes in a continuous stirred tank reactor are compared to those in a tube reactor.
