Unsteady potential flows computation by cellular automata : The premixed flame instability
A cellular automaton leading to self-propagating fronts in a discrete fluid has been implemented. In spite of the stabilising diffusive-convective mechanisms, planar propagation of these fronts becomes unstable due to a feed-back mechanism with the flow generated by the front itself. The stability properties have been analysed in the continuum limit and compared with the discrete simulations as well as with the stability properties of premixed flame fronts.
