Pressure dependence of sooting characteristics of m-xylene and n-octane doped laminar methane diffusion flames from 2 to 10 bar

Influence of sub-atmospheric pressure on flame shape and sooting propensity in ethylene laminar coflow non-premixed flame

“…That being said, the rate of the increase depends on several characteristics at very different scales, from fuel composition to flame shape or pressure range. Numerous studies have focused on the pressure/soot production relationship [3,[5][6][7][8][9][10][11][12][13][14][15][16]. In order to characterize the trend, many authors have established a relation of the following type:…”

Coupling Analysis of Chemiluminescence and Pressure Changes in CH4/Air Explosion Suppressed by NaHCO3 Powder

“…Then, Liu 26 studied the luminescence characteristics of OH* and CH* in the methane flame under the action of water mist and found that the emission spectrum intensity decreased with the increase of the water mist load ratio of the flame front. Yang 27 first observed and measured the characteristic spectrum of the methane flame under the action of powder inhibitor through a camera device and a spectrum testing instrument. With the addition of four kinds of suppressants including fumed silica, ultrafine ABC dry powder, sodium bicarbonate, and potassium bicarbonate powders, he observed and analyzed the change of the free radical characteristic spectrum in the flame.…”
