CH(A-X) and OH(A-X) Optical Emission in an Axisymmetric Laminar Diffusion Flame
نویسندگان
چکیده
Steady-state concentrations of electronically excited CH(AD) and OH(A¥) are extracted from previous quantitative measurements of optical emission from an axisymmetric laminar diffusion flame [K. T. Walsh, M. B. Long, M. A. Tanoff, and M. D. Smooke, Twenty-Seventh Symposium (International) on Combustion, The Combustion Institute, Pittsburgh, 1998, pp. 615–623]. The flame is modeled with a two-dimensional transport and detailed chemistry explicitly augmented with the reactive, radiative, and energy transfer collisional processes to produce and remove electronically excited CH(A) and OH(A). Computations predict concentrations of CH(A) and OH(A) which agree with the measurement within a factor of 6 or better, a significant improvement compared to the earlier report. © 2000 by The Combustion Institute

Optical Emission Tomography of Non-axisymmetric, Laminar, Premixed Flames
Optical emission tomography of flames has recently been demonstrated as a practical experimental technique for determining the instantaneous position of a 3D flame surface. In this paper, optical emission tomography is applied to steady and forced, non-axisymmetric, premixed, laminar flames. An experimental set-up involving a single camera and a rotatable flame holder allows camera images from ...
متن کاملEffect of light-collection geometry on reconstruction errors in Abel inversions.
The Abel inversion, used to reconstruct axisymmetric radial profiles from line-of-sight intensity measurements, is increasingly used to make spatially resolved combustion measurements. An Abel deconvolution is valid only when incoming rays are parallel, whereas most practical optical setups used for emission imaging consist of single-lens and multilens systems that collect light in a cone, over...
متن کاملInteractions between soot and CH in a laminar boundary layer type diffusion flame in microgravity
A three-dimensional laminar non-buoyant diffusion flame was studied with the objective of improving the understanding of the soot production. The flame originated from a porous ethylene burner discharging into a laminar boundary layer. Soot volume fractions were measured using Laser-Induced Incandescence (LII) and the spontaneous emission from CH∗ was determined using chemiluminescence. The mai...
متن کاملExperimental investigation on soot volume fraction in an ethylene diffusion flame by emission spectrometry without optically-thin assumption
An improved soot diagnostics technique based on tomographic reconstruction of flame emission spectra has been developed for an axisymmetric laminar diffusion flame without optically-thin assumption. Emission from the flame is scanned along the horizontal lateral axis of flame at several altitudes above the burner. At each measurement position, the local line-of-sight flame emission spectra is c...
متن کاملSimultaneous CH planar laser-induced fluorescence and particle imaging velocimetry in turbulent nonpremixed flames
We report the simultaneous measurement of the flamefront location, using single-shot CH planar laserinduced fluorescence (PLIF), and the velocity field, using two-color digital particle imaging velocimetry (PIV), in nonpremixed turbulent flames. To minimize the influence of particle scattering on the CH PLIF images, we pump a CH B-X(0,0) transition at 390 nm and detect A-X fluorescence at 420–4...
