Six methane/air flames of equivalence ratio 0.7, Ka =1–17 stabilized on a intense turbulence low-swirlburner of were investigated by Rayleigh laser sheet measurements of the gas density within the preheat zone (approximately 400–1000 K). Lean pre

Burning rate measurements have been performed in lean (φ = 0.7) premixed methane/air flames stabilized on a low-swirl burner in moderate and intense turbulence, (Ret = 460–1400). The purpose of this paper is to reconcile the burning rate determine

The local scalar statistics of premixed flames in turbulent opposed streams has been studied by sheet laser tomography. The statistics collected on these flame edges provide information on the mean flame position, and the mean and standard deviations

The flame surface density has been measured in hydrocarbon/air stagnation point and v-shaped premixed turbulent flames. A method is proposed to determine the flame surface density from the data obtained by laser sheet tomography. The average flame le

A method is proposed to measure the burning rate of planar premixed turbulent flames in stagnation flows. The method is based on the balance of conditional mass fluxes in a control volume that extends from pure reactants to the stagnation plane. The

Numerical and experimental results are presented to demonstrate some effects of heat release in open premixed flames, especially the strain induced in the reactant flow field. A simple model represents the heat release by treating the flame front as

This study presents a means of determining the burning rate of non-one-dimensional premixed turbulent flames based on fundamental conservation principles, which breaks with the convention of using a cold boundary mass flux. The approach is through di

Experimental and numerical determinations of flame front curvature and orientation in premixed turbulent flames are presented. The experimental data is obtained from planar, cross sectional images of stagnation point flames at a high Damkohler number

The stabilization of a premixed, turbulent V-shaped flame on a bluff body has been studied using laser Doppler anemometry for two-compenent velocity data, and Rayleigh scattering for point measurements of density. The conditions studied include isoth

The influence of burner geometry on premixed turbulent flame propagation has been studied experimentally by investigating the turbulent transport, turbulence production and burning rate in three flame configurations: they are rod-stabilized v-flames,
