Abstract

Chaotic oscillations have been observed experimentally in dual-frequency oscillator OAP - Ce⁺⁴-BrO⁻₃-H₂SO₄ in CSTR. The system shows variation of oscillating potential and frequencies when it moves from low frequency to high frequency region and vice-versa. It was observed that system bifurcate from low frequency to chaotic regime through periode-2 and period-3 on the other hand system bifurcate from chaotic regime to high frequency oscillation through period-2. It was established that the observed oscillations are chaotic in nature on the basis of next amplitude map and bifurcation sequences.
