Flame Balls in a non-uniform reactive mixture: preferential diffusion, heat-loss and stability

The paper examines the existence and stability of axisymmetric flame balls in a non-uniform reactive mixture corresponding to a mixing layer taking into account preferential diffusion and volumetric heat-loss. The mixture's non-uniformity is measured with a non-dimensional parameter ε which is inversely proportional to the square root of the Damköhler's number. The investigation is carried out analytically in the limit of large activation energy...
