This research is a product of the Department of Physics faculty at Indiana University-Purdue University Fort Wayne. We present a theory for the transition from nonaxisymmetric to axisymmetric convection in iodatearsenous acid reaction fronts propagating in a vertical slab. The transition takes place away from the onset of convection, where a convectionless flat front becomes unstable to a nonaxisymmetric convective front. The transition is studied by numerically solving a reaction-diffusion equation coupled with nonlinear hydrodynamics in a two-dimensional slab. PACS number(s): 47.20.Bp, 47.70.Fw, 82.20.Mj
