An experimental study on the spectral dependence of light extinction in sooting ethylene counterflow diffusion flames

An experimental study has been conducted in premixed and counterflow diffusion flames in order to obtain the nanocarbon materials. In this paper the synthesis of fullerenes, carbon nanotubes and superhydrophobic soot surface in the regime of hydrocarbon flames were studied. The original results in the field of synthesis of fullerenes, carbon nanotubes and syperhydrophobic soot in hydrocarbon flames were carried out for the last years at the Institute of Combustion Problems.

Counterflow Diffusion Flame

A cost-effective and straightforward light extinction method has been extensively used for measurement of soot volume fraction (SVF) in sooting flames. The traditional pointwise measurement with translation stage suffers from relatively time-consuming operation and low spatial resolution. In the current study, the planar light extinction method is processed by utilizing a CMOS camera to image the combustion field of counterflow diffusion flame (CDF) backlit with the lamp. Collimated and diffuse optical layouts were adopted to explore the feasibility. Investigations of beam-steering effects are presented and discussed through a combination of computational fluid dynamics (CFD) and ray tracing simulations. Measured SVF are compared to the well-validated laser-induced incandescence (LII) measurements. Current measurements show that the diffuse optical layout is feasible and robust to provide accurate and more efficient measurement of the SVF in CDF with superior spatial resolution (21.65 μm).
