Bloch-front turbulence in a periodically forced Belousov-Zhabotinsky reaction Academic Article uri icon

abstract

  • Abstract Experiments on a periodically forced Belousov-Zhabotinsky chemical reaction show front breakup into a state of spatiotemporal disorder involving continual events of spiral- vortex nucleation and destruction. Using the amplitude equation for forced oscillatory systems and the normal form equations for a curved front line, we identify the mechanism of front breakup and explain the experimental observations.
