Abstract

The diffusively unstable premixed gas flame is shown to be strongly affected by the background shear flow tangent to the flame interface. The pertinent flame-flow interaction alters both the flame stability limits and the character of its nonlinear evolution. The shear flow may expand the limits of the flame's diffusive instability simultaneously inducing new nonlinear saturation and linear dispersion effects similar to those occurring in KdV systems.
