Experimental studies on the weak coupling of oscillatory chemical reaction systems

Abstract

The interactions of two coupled oscillating systems of the Belousov–Zhabotinsky chemical reaction were investigated experimentally. A mapping diagram of coupling was experimentally obtained in the plane of ω₂/ω₁ and S_1–2 where ω₁ and ω₂ were the natural frequencies of reactor 1 and 2, S_1–2 was the area of the window that coupled the two reactors. The irregular synchronization region in this diagram may correspond to Tomita and Kai’s region χ where a chaotic response has been predicted.
