Abstract
A linear convective stability analysis for propagating autocatalytic r eaction fronts includes density differences due to both thermal and ch emical gradients. Critical parameters for the onset of convection are calculated for an unbounded geometry, a vertical slab, and a vertical cylinder. Thermal effects are important at unstable wavelengths well a bove the critical wavelength for the onset of convection. (C) 1995 Ame rican Institute of Physics.
