Network structure of turbulent premixed flames
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2017In this paper, a generalized description of the complex topology of turbulent premixed flames stabilized in a model gas turbine combustor is obtained using network analysis. Networks are created using the visibility algorithm applied to points on the flame edge obtained from Hydroxyl radical (OH)—Planar Laser Induced Fluorescence images of turbulent ...

The structure of Bunsen cone flame tops is studied using the thermal diffusion flame model. Assuming a strong temperature dependence of the reaction rate, the shape of the flame front as well as the temperature distribution at the front are found. It is shown that for the case in which the Lewis number of the limiting component is greater than unity ...

Studies of the structure of sooting flames have provided valuable information about chemical and physical processes occurring prior to and during soot formation. These studies have included both laminar and turbulent premixed and diffusion flames, thus permitting sooting behavior to be compared and contrasted for various conditions of practical and ...

Symposium (International) on Combustion, 1991
The one-dimensional formulation of the opposed flow strained flame problem, starting from the cylindrical Navier-Stokes equations, is described and compared with the older, Hiemenz potential flow formulation. The eigenvalue in the newer formulation is shown to be a stress on the fluid, and it is shown that the Navier-Stokes equations reduce to ...

Structure and extinction of diffusion flames with flame radiation
Symposium (International) on Combustion, 1991Using droplet combustion as a model problem, and capitalizing on the temperature-sensitive nature of radiative heat transfer, the structure and extinction of diffusion flames with flame radiation is studied via multi-scale activation energy asymptotics.

Local Flame Structure in Hydrogen-Air Turbulent Premixed Flames
2002Local flame structures of the turbulent premixed flame are discussed. The study is based on the hydrogen transport near the flame front using DNS data of three-dimensional H2-air turbulent premixed flame under the condition of u′ /S L = 1.74 and l/ δ L = 2.00.

Burning velocities of a number of slow-burning, fuel-rich hydrogen + nitrogen + oxygen flames have been measured and compared with values computed on the basis of the chemical mechanism proposed by Dixon-Lewis (1970 a ).
