Abstract
Observations of steady nonaxisymmetric chemical wave fronts are report ed for upward propagation in iodate-arsenous acid solutions within ver tical capillary tubes. These observations confirm a recent prediction of hydrodynamic stability theory that the onset of convection in such fronts should be nonaxisymmetric. The nonaxisymmetric waveform reflect s the presence of a single convective roll in the vicinity of the movi ng front.
