Non Linear Analysis of Traveling Waves in Binary Convection
Much effort has been devoted recently to the phenomenon of convection in binary mixtures. A rich variety of dynamical states has been found experimentally1–5. Contrary to what happens for pure fluid convection the conducting state gets destabilized at finite frequency through a Hopf bifurcation6. In certain circumstances, a system of propagative rolls appears, with a subcritical transition when the control parameter is increased. These traveling waves have non trivial interactions that lead to novel and rather complex phenomena. Binary mixture convection is therefore an appropriate tool for studying chaotic behavior in large physical systems and the so called ‘weak turbulence’ regime.
