摘要：

The nonlinear evolution of a weakly perturbed planar flame under the influence of the Landau-Darrieus instability is studied numerically. It is shown that in sufficiently small-scale systems spontaneous instability appears in the guise of a cusp-shape flame. However, in sufficiently large-scale flames this configuration acquires a fine cellular structure with the cells constantly subdividing and merging in a chaotic manner. © 1990.
