Ruelle-Takens-Newhouse scenario in reaction-diffusion-convection system / Budroni, M. A.; Masia, Marco; Rustici, Mauro; Marchettini, N; Volpert, V. AND CRESTO P. C.. - In: THE JOURNAL OF CHEMICAL PHYSICS. - ISSN 0021-9606. - 128:(2008), pp. 111102-1-111102-4. [10.1063/1.2894480]
Abstract:
Direct numerical simulations of the transition process from periodic to chaotic dynamics are
presented for two variable Oregonator-diffusion model coupled with convection. Numerical
solutions to the corresponding reaction-diffusion-convection system of equations show that natural
convection can change in a qualitative way, the evolution of concentration distribution, as compared
with convectionless conditions. The numerical experiments reveal distinct bifurcations as the
Grashof number is increased. A transition to chaos similar to Ruelle–Takens–Newhouse scenario is
observed. Numerical results are in agreement with the experiments.
