Detailed bifurcation structure and new mixed-mode oscillations of the Belousov–Zhabotinskii reaction in a stirred flow reactor

Abstract

The experimental behaviour of the Belousov–Zhabotinskii reaction in a continuously stirred tank reactor is examined. We present a complete, systematic listing of results gained for residence times in between two values of a stable stationary state, and discover an absence of symmetry about period-one oscillations. Particular attention is paid to chaotic behaviour at long residence times and its analysis. Two new mixed-mode oscillatory states are described phenomenologically by the use of slow manifolds.
