CHAOS IN PARAMETRIC RESONANCE FLOW AT WATER-MERCURY INTERFACE

In the electrochemical system with liquid-liquid interface, intense lo cal convections by the resonance with potential pulses take place. The refore, with laser beam scattering, temporal movement of the water-mer cury interface was observed. As a result, the scattering efficiency sh owed non-linear oscillation. Such non-linear response could be control led by potential pulse height. As the potential height was increased, new scattering peaks in the oscillation emerged, which was expected of a kind of bifurcation phenomenon. From these results, phase portrait, Poincare section, correlation dimension of the strange attractor and the largest Lyapunov exponent of the trajectories were obtained. Conse quently, it was concluded that all the parameters indicate chaotic beh avior of the resonance flow.
