The Bray-Liebhafsky (BL) is one of the most analyzed oscillatory reaction both experimentally and
numerically. Most of the experimentally obtained dynamical states of this reaction realized in a
continuously fed well stirred tank reactor (CSTR) are successfully simulated. Beside others,
numerous structured chaotic dynamical states were obtained between each two periodic states in the
period doubling rout to chaos with respect to specific flow rate as the control parameter. It was an
universal scenario throughout the whole mixed-mode region, as well as throughout other mixed-mode
regions obtained under different initial conditions. However, the intermittent oscillations consistent
of chaotic mixture of large-amplitude relaxation oscillations, grouped in bursts and small-amplitude
sinusoidal ones or even quiescent parts between them known as gaps were also generated
experimentally in the Bray–Liebhafsky reaction by varying different parameters such as temperature,
flo...w rate or reactant concentrations under CSTR conditions. Nevertheless, it will be shown here that
intermittent oscillations can be simulated by already published model of the BL reaction network.
