Effect of Damkohler Number and Non-Unity Lewis Number on a Laminar Diffusion Flame [PDF]
Volume 1: Fora, Parts A, B, C, and D, 2003 The effect of the Damkohler number (Da) and non-unity Lewis number on a two-dimensional, steady, laminar diffusion flame anchored by a dividing plate in a rectangular channel was considered. The governing equations were solved numerically, using the SIMPLE and ADI schemes.

The effect of Lewis number on the stability of a catalytic reaction
AIChE Journal, 1970AbstractAn extensive numerical study was carried out to determine the effect of Lewis number on the stability of a chemical reaction occurring inside a porous catalyst pellet. It is found that when the Lewis number is different from 1, the coupling between the concentration and temperature causes several pathological effects during the transient ...

Analysis of Lewis number effects in flame spread
International Journal of Heat and Mass Transfer, 1993De Ris's formulation of the problem of flame spread over thin and thick solid fuel surfaces is extended to include the influence of nonunity Lewis numbers of oxidant and fuel vapors. A zeroth order formula for the flame spread velocity is deduced. To this order of approximation, the Lewis number of the oxidant affects the spread rate only through its ...

Lewis number effects on turbulent burning velocity
Symposium (International) on Combustion, 1985Experimental values of turbulent burning velocities for propane, hydrogen and iso-octane mixtures with air are reported under conditions of high turbulence and high turbulent Reynolds number. The measurements were made by the double kernel method during explosions in a fan-stirred bomb, with four fans, capable of speeds of up to 10,000 rpm.

Anomalous lewis number effects in tribrachial flames
Symposium (International) on Combustion, 1989Tribrachial (three-armed) flames are generated when a premixed flame propagates into a nonuniform mixture, and consist of a fuel-rich branch joined to a fuel-lean branch, with a diffusion flame trailing from the junction (the stoichiometric point). They are important in the context of ‘laminar flamelet’ models of turbulent non-premixed flames.

Lewis-number effects on edge-flame propagation
Journal of Fluid Mechanics, 2002Activation-energy asymptotics is employed to explore effects of the Lewis number, the ratio of thermal to fuel diffusivity, in a one-dimensional model of steady motion of edges of reaction sheets. The propagation velocity of the edge is obtained as a function of the relevant Damköhler number, the ratio of the diffusion time to the chemical time ...

Analysis of Lewis number effects on dynamic response of laminar premixed flames [PDF]
Combustion and Flame, 2023 The dynamic response of premixed flames with different fuel Lewis numbers is crucial to understand for the design of safe combustion chambers with wide operating range.
