Control of spiral instabilities in reaction – diffusion systems *

Spiral instabilities and their controls are investigated in a reaction–diffusion system using the Belousov–Zhabotinsky reaction. Two spiral instabilities, the long-wavelength instability and the Doppler instability, are reported, which can lead to spatiotemporal chaos. The long-wavelength instability occurs in an oscillatory regime, while the Doppler… CONTINUE READING
