Effect of Stretch on Local Burning Velocity of Premixed Turbulent Flames
Journal of Thermal Science and Technology, 2007 The effect of positive stretch on the local flame properties of turbulent propagating flames in the flamelet regime was investigated experimentally for methane-, hydrogen- and propane-air mixtures with lean and rich having nearly the same laminar burning

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.

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/

The Behavior of Lewis Number in Finned Tube Cooling Coils under Highly Moist Inlet Air Conditions
International Journal of Technology, 2016 The objective of this research was to study the effects of highly moist inlet air conditions such as temperature, relative humidity, and frontal air velocity on the value of the Lewis number (Le) in the cooling and dehumidifying process of air.
