This is a two-dimensional model from chemical reaction engineering. It models the dynamics of a single reaction
in a stirred tank reactor. The two state variables are u the concentration of species A, and v, the temperature. The model equations are given below.
This model has three parameters, , , and . The parameters and are always non-negative. The parameter is positive if the reaction is exothermic (releases heat) or negative if the reaction is endothermic (absorbs heat).
This model can exhibit rather rich behavior, and is not especially easy to work with, due mostly to the exponential nonlinearity. To help you in your investigations, I would suggest that you fix and restrict to the range .
