The structure of flame filaments in chaotic flows [PDF]
, 2002 The structure of flame filaments resulting from chaotic mixing within a combustion reaction is considered. The transverse profile of the filaments is investigated numerically and analytically based on a one-dimensional model that represents the effect of

Effect of Lewis number on premixed laminar lean-limit flames stabilized on a bluff body
Proceedings of the Combustion Institute, 2019 In this paper, we present a study on the effect of Lewis number, Le, on the stabilization and blow-off of laminar lean limit premixed flames stabilized on a cylindrical bluff body.

Journal of Fluid Science and Technology, 2013 We studied numerically the intrinsic instability of high-temperature premixed flames, where the burned-gas temperature was constant, under the conditions of constant density and constant pressure in the unburned gas.

High Lewis Number Combustion Wavefronts: A Perturbative Melnikov Analysis [PDF]
SIAM Journal on Applied Mathematics, 2007 The wavefronts associated with a one-dimensional combustion model with Arrhenius kinetics and no heat loss are analyzed within the high Lewis number perturbative limit. This situation, in which fuel diffusivity is small in comparison to that of heat, is appropriate for highly dense fluids.

Triple flames in mixing layers with nonunity lewis numbers [PDF]
Symposium (International) on Combustion, 1998 The present paper is devoted to the study of the effects of nonunity Lewis numbers on triple-flame propagation in nonuniform mixtures. For definiteness, the case of a strained reactive mixing layer is considered. The fuel and oxidizer that are fed to the mixing layer are allowed to have different initial temperatures.

Constitutional Fidelity, The Rule of Recognition, and the Communitarian Turn in Contemporary Positivism [PDF]
, 2006 Contemporary positivism has taken a communitarian turn. Hart, in the Postscript to the Concept of Law, clarifies that the rule of recognition is a special sort of social practice: a convention.

Lewis Number Effects on Turbulent Premixed Flame Structure [PDF]
Combustion Science and Technology, 1993 ABSTRACT The influence of the Lewis number on turbulent flame front geometry is investigated in a premixed turbulent stagnation point flame. A laser tomography technique is used to obtain the flame shape, a fractal analysis of the multiscale flame edges is performed and the distribution of local flame front curvature is determined. Lean H2/Air and C3H8/
