On PAH formation in strained counterflow diffusion flames
Combustion and Flame, 2001The structural response of methane/air and methane-nitrogen/air counterflow diffusion flames to strain was investigated by measurements and computations. The numerical predictions were found to be in reasonably good agreement with the experiments. Different reaction pathways leading to PAH formation are examined computationally to obtain a deeper ...

Ultrafine Refractory Particle Formation in Counterflow Diffusion Flames
Combustion Science and Technology, 1992Abstract The effect of process variables (percursor concentration, residence time, temperature, and electric field) on ceramic powder formation was studied using a counterflow diffusion dame burner. GeCl4 and SiCl4 were used as source materials for the formation of Ge02 and Si02 in hydrogen—oxygen flames.

Effects of Soret Diffusion on Premixed Counterflow Flames
Combustion Science and Technology, 2015Soret diffusion is a secondary mass diffusion and it affects laminar flames with very light or heavy species and large temperature gradients. To get a general understanding of Soret effects on stretched flames, we conduct theoretical analysis on a premixed counterflow flame with Soret diffusion. A deliberately idealized premixed counterflow flame model

Laser Induced Fluorescence in Inhibited Counterflow Diffusion Flames
Laser Applications to Chemical, Security and Environmental Analysis, 1998As part of the continuing effort to find an effective, yet safe, replacement compound for the commonly used halon fire suppression agents, we have begun a study of reduced pressure counterflow diffusion flames inhibited with iron pentacarbonyl (Fe(CO)5). Iron pentacarbonyl has been shown to be a very effective fire suppression agent in small quantities,

Extinction of Counterflow Diffusion Flame in High Pressures
Combustion Science and Technology, 1991Extinction of the counterflow diffusion flame in high pressures has been studied experimentally up to the ambient pressure of 10 MPa. Oxidizer was air and fuels were methane, ethane. carbon monoxide, carbon monoxide/hydrogen mixtures. Experimental results have shown that the critical stagnation velocity gradients for the methane and ethane are about ...

Effects of Non-Equilibrium Plasma on Counterflow Diffusion Flames
48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010A new plasma assisted combustion system was developed by integrating a counterflow burner with nano-second pulsed non-equilibrium plasma. Xenon calibrated two-photon absorption laser-induced fluorescence was used to characterize the system by measuring the absolute atomic oxygen concentrations at the exit of the counterflow burner.

Sooting Characteristics and Modeling in Counterflow Diffusion Flames
2013Soot formation is one of the most complex phenomena in combustion science and an understanding of the underlying physico-chemical mechanisms is important. This work adopted both experimental and numerical approaches to study soot formation in laminar counterfl ow diffusion flames.
