Flame Curvature Statistics in Axisymmetric Turbulent Jet Flames

Combustion Science and Technology, 1995
ABSTRACT Flame curvature in axisymmetric turbulent jet flames are obtained experimentally for u'/S L from 0.8–1.5. The measurements indicate that the flame curvature statistics exhibit a substantial change as a function of the axial location in turbulent jet flames primarily due to the evolution of flame wrinkle structures.

Flame Front Curvature Distributions in a Turbulent Premixed Flame Zone

Combustion Science and Technology, 1997
Distributions of flame front curvature obtained by laser sheet tomography agree with those derived from numerical simulations of passive flame propagation within three-dimensional Navier-Stokes turbulence. The experimental configuration is that of grid turbulence impinging upon a plate which stabilizes a premixed methane/air flame, planar images of the

The numerical simulation of fuel-lean counterflow premixed flame with flame curvature

Progress in Computational Fluid Dynamics, 2010
Summary: Numerical simulations of counterflow premixed flames with flame curvature were carried out. To impart a flame curvature, the premixed gas was ejected from the nozzle with axial velocities varying in the transverse direction. The influence of the flame curvature, unsteady behaviour and flame structure on local extinction was investigated.

The curvature Markstein length and the definition of flame displacement speed for stationary spherical flames

Proceedings of the Combustion Institute, 2015
Abstract The separate effects of flame stretch and flame curvature are investigated in the present study considering a stationary spherical flame configuration that experiences no stretch but has a finite curvature. A theoretical expression for the flame displacement speed, derived from asymptotic analysis, is compared with numerical simulations ...
