详细

For a countercurrent liquid–liquid plug reactor, theoretical studies of the implementation of possible types of stationary states were carried out. States such as a stable node and focus, and an unstable focus with a stable limit cycle (oscillations) have been discovered. Using these data, the evolution of stationary states with continuous changes in external control parameters was studied. When the relationship between the flow rates of the phases changes, a structure of stationary states is discovered, which can be realized both at the entrance and exit of the dispersion medium.
