M. Gomezgesteira et al., BOUNDARY-IMPOSED SPIRAL DRIFT, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 53(5), 1996, pp. 5480-5483
The spiral wave behavior was examined in a bounded medium within the f
ramework of the Belousov-Zhabotinsky reaction. When the spiral tip was
located far from the center of a circular medium, the spiral wave was
observed both to drift along the boundary and to approach it.
