Abstract

To further understand the flamelet regime of turbulent combustion, the interaction between adjacent flame surfaces of a wrinkling laminar premixed flame was studied. The wrinkling flame was formed with three adjacent laminar V-shaped flames stabilized on a multiple-slit burner of a propane/air mixture. A single V-shaped flame was also formed on the burner. Flame shapes and flow velocity distributions between those two types of flames were compared. The convex flame surface toward unburned side expanded the unburned flow field outwardly. The inner convex flame of the wrinkling flame formed on the burner was more unstable than the single convex flame. The pure curvature effect caused the change of the burning velocity. In the wrinkling flame, the expansion at the upstream of the convex flame was smaller than that of the single V-shaped flame, so that it was difficult for its convex flame to form. This is an abstract of a paper presented at the 29th International Symposium on Combustion (Sapporo, Japan 7/21-25/2002).
