Modeling Front Pattern Formation and Intermittent Bursting Phenomena in the Couette Flow Reactor

摘要: In the last decade there has been increasing interest in pattern forming phenomena chemical systems [1–12]. early eighties a great deal of attention paid to dynamics homogeneous reactions. well-mixed media, intrinsic nonlinear nature kinetics provided field experimentation for study low-dimensional dynamical [5]. When maintained far from thermodynamic equilibrium continuously stirred tank reactor (CSTR), reactions have shown exhibit transition coherent (periodic) temporal patterns chaos [13]. Among these oscillators, Belousov—Zhabotinsky (BZ) reaction [14] revealed most well-known scenarios including period-doubling, intermittency, frequency locking, collapse tori and crisis [15, 16]. contrast, until very recently, experiments on spatial spatio-temporal formation reaction-diffusion performed closed where system uncontrollably irreversibly relaxed equilibrium. Therefore applicability were limited transient developing rather short time, practice those resulting excitability such as so-called target spiral waves [5–7, 10, 11, 17–20].
