Cascading Cellular Flames

SIAM Journal on Applied Mathematics, 1989
Summary: The problem of a flame stabilized by a line source of fuel of strength \(2\pi\) \(\kappa\) is solved numerically. As \(\kappa\) is varied, first a bifurcation from an axisymmetric solution to a stationary cellular solution is found. Increasing \(\kappa\) further, a sequence of transitions to stationary cellular solutions of increasing mode ...

Localized Flickering Cellular Flames

SIAM Journal on Applied Mathematics, 1998
Summary: We illustrate the formation and evolution of cellular flames described by localized, ordered solutions of a modified Kuramoto-Sivashinsky equation (MKSE) derived for flames stabilized on a burner. The MKSE equation accounts for a slight curvature of the flat front due to the slowing of the gas flow near the burner rim.

Cellular and Tulip Flame Configurations

Journal of Applied Mechanics and Technical Physics, 2003
Flame propagation in a plane channel with the formation of tulip and cellular configurations of the combustion front is simulated. The near-flame flow structure and the thermal flow structure are determined. An analogy is found between the tulip configuration and flame inflections at cell interfaces.

Nonlinear Dynamics of Cellular Flames

SIAM Journal on Applied Mathematics, 1992
The problem of a flame stabilized by a line source of fuel in the cellular regime, i.e., $L < 1$,where L is the Lewis number, is solved numerically. It is found that as L is decreased, transitions from stationary axisymmetric to stationary cellular to nonstationary cellular flames occur.
