In this work, it is shown that, despite the low reactivity of petroleum coke (petcoke) and the presence of 40% water, a petcoke suspension having a large colloidal population burned with unpreceden...

The secondary reactions of volatile compounds, including coal tar and light gases, accounts for a great portion of soot formation and the subsequent heat release and pollutant emissions in the combustion zone. While coal primary pyrolysis has been ex

Premixed tubular flames with different fuels (H 2 , CH 4 and C 3 H 8 ) mixed with air are investigated using visible laser-induced spontaneous Raman spectroscopy. Two sets of sub-unity Lewis number H 2 /air flames with Φ = 0.175, k = 145–363 s −

∗+ & Tubular diffusion flames are compared with opposed jet diffusion flames numerically to show the effect of curvature on diffusion flames. The numerical results show that, as in premixed flames, positive curvature strengthens the preferential di

The counterflow flame system established between lean-methane–air and lean-hydrogen–air streams is investigated experimentally and numerically. A two-dimensional model known as UNICORN was used for the simulation. Detailed measurements for temper

Non-premixed tubular flames are established using the opposed tubular burner for the first time, which enables the quantitative study of curvature effects on flame behavior. A detailed structural investigation using the spontaneous Raman scattering t

A compact micro-lens optical system is developed that produces a 7×7 multi-line optical grid for Hydroxyl Tagging Velocimetry (HTV) and generates at least 49 resolvable velocity vectors. Single-photon photodissociation of ground-state H2O by a ~193-

*† ‡ An experimental study of cellular instability of non-premixed tubular flames was conducted on a newly designed opposed-flow tubular burner. In this study, H2 diluted by CO2, N2, Ar or He was used as fuel and burned against air in a cylindric

Extinction and cellular instabilities are investigated in premixed tubular flames. A tubular burner has recently been designed and constructed to be capable of operating under a wide range of conditions that allow more accurate and detailed study of
