Dynamic States of Cellular flames
arXiv:0910.3183
Abstract
A premixed flame on a circular porous plug burner can form cellular flames, which are ordered patterns of concentric rings of brighter, hotter regions separated by darker, cooler cusps and folds. These ordered states bifurcate to dynamic states in which the cells move in coordinated motion. Fluid dynamics videos of representative examples of these states will be presented. Videos of all the dynamic states of premixed flames can be found at [http://www.uh.edu/~mgorman].
