Darrieus–Landau instability

The Darrieus–Landau instability refers to a type of instability that can occur in a flame front, particularly in the context of combustion processes. It describes the behavior of a planar flame as it becomes unstable and develops into a wrinkled or fractal structure. This phenomenon is often observed in premixed flames, where fuel and oxidizer are mixed before combustion, and involves the interaction between chemical reactions and fluid dynamics.
