Modelisation and Forecast of Premixed Flames
Abstract eng: We demonstrate here the possibility to compare the evolution of an analytical flame corresponding to a pole solution of the Sivashinsky equation with the evolution of an experimental flame. The experiment used as a benchmark consists of the propagation of a quasi two-dimensional propane-air flame in a Hele-Shaw burner. A best approximation of the experimental flame at an initial time is first calculated by fitting with a limited series of pole-based functions. The trajectories of the poles are then integrated numerically in time and the evolution of the front they are representing is finally compared with the evolution of the experimental flame.
