Onset of convection for autocatalytic reaction fronts: Laterally bounded systems

Convective Instability of Autocatalytic Reaction Fronts in Vertical Cylinders

Dispersion curves in the diffusional instability of autocatalytic reaction fronts.

A (linear) stability analysis of planar reaction fronts to transverse perturbations is considered for systems based on cubic autocatalysis and a model for the chlorite-tetrathionate reaction. Dispersion curves (plots of the growth rate sigma against a transverse wave-number k) are obtained. In both cases it is seen that there is a nonzero value D0 of D (the ratio of the diffusion coefficients o...
