title = "Propagation of lean premixed polydispersive spray flames",
abstract = "A new numerical study of the propagation of laminar lean premixed polydisperse spray flames in a two-dimensional channel is presented. A constant density model is adopted in order to isolate thermal-diffusional effects through elimination of instabilities of the Darrieus-Landau type. Due to the numerical solution linearization is not necessary for examining flame instabilities. The impact of the initial size distribution on the stability of flame propagation is investigated for two quite different initial size distributions having the same Sauter mean diameter. It is found that the initial droplet size distribution can exert a strong influence on the average flame speed, both spatial and time-wise instabilities and their onset. In addition, even for the same size distribution the mode of flame propagation is influenced by the actual initial perturbation and, here, was shown to be attracted to one of two unsteady limiting modes, (unsteady limiting modes).",
