Modelling of a premixed flame by means of a cellular automaton
A cellular automaton that simulates the propagation of a premixed flame front has been implemented. The potential role of the flame self-generated flow is analysed, leading to the development of the Landau instability in initially planar fronts. Temporal evolution of non-planar cellular flames has been studied and the non-linear modal energy distribution characterised by the Fourier transform of the distorted front position. An inverse energy cascade has been observed corresponding to the growth of the small disturbances to larger size structures. Moreover, this automaton is shown to be a useful and effective tool to compute any general unsteady potential flow.
