Abstract

In this note we derive an evolution that models the spontaneous instability of a flame front which, although formally correct to the same order as the Kuramoto-Sivashinsky equation, contains a meaningful modification coming into play primarily in regions of large gradients. The approach used is a regularization procedure that modifies the conventional expansion procedure which fails whenever the gradients become large; the new equation is believed to better describe the formation of patterns on the flame front.
