Abstract
We present a theory for the transition from nonaxisymmetric to axisymm etric convection in iodate-arsenous acid reaction fronts propagating i n a vertical slab. The transition takes place away from the onset of c onvection, where a convectionless flat front becomes unstable to a non axisymmetric convective front. The transition is studied by numericall y solving a reaction-diffusion equation coupled with nonlinear hydrody namics in a two-dimensional slab.
