Long Range Interaction of Vortices in a Chemical Active Medium

[Netsu Sokutei, Vol.24, No.4, pp.194-198, 1997]


Experimental study and computer simulations of interaction of vortices in the Belousov-Zhabotinsky reaction show that a small difference in the frequency of vortex rotation causes a marked drift of a vortex with lower frequency. The trajectory of the drift is a logarithmic spiral. Analytical estimations are in a good agreement with the experimental results.
