Soot Formation in Laminar Diffusion Flames
Laminar, sooting, coflow diffusion flames at atmospheric pressure have been studied experimentally and theoretically as a function of fuel dilution by inert nitrogen. The flames have been investigated with laser diagnostics. Laser extinction has been used to calibrate the experimental soot volume fractions and an improved gating method has been implemented in the laser-induced incandescence (LI...
متن کاملImaging Measurements of Soot Temperature and Volume Fraction in Flames
New diagnostics are presented that use a digital camera to measure full-field soot temperatures and soot volume fractions in axisymmetric flames. The camera was a Nikon D700 with 12 megapixels and 14 bit depth in each color plane, and was modified by removing the infrared and anti-aliasing filters. The flame considered here was an 88 mm long ethylene/air coflowing laminar jet diffusion flame on...
متن کاملModeling soot formation in turbulent kerosene/air jet diffusion flames
Soot volume fraction and number density in a turbulent diffusion flame burning kerosene/air were predicted using two approaches. The first used a conventional soot inception model based on the acetylene concentration and is referred to as the acetylene model. The second used a soot inception model based on the formation rate of three and two ring aromatics [1] and is referred to as the PAH ince...
متن کاملTwo-dimensional imaging of soot volume fraction and OH in turbulent jet diffusion flames spanning low to high mixing rates
Simultaneous planar measurements of laser-induced incandescence (LII) and Laser-Induced Fluorescence of OH radical were carried out in turbulent jet flames from a simple jet, precessing jet and bluff body burner firing natural gas. These flames span a wide range of global mixing rates and sooting characteristics, and are selected because measurements of total NOx emissions, radiant fraction and...
متن کاملReaction mechanism of soot formation in flames
The formation of polycyclic aromatic hydrocarbons (PAH) and soot has become one of the central themes of research activities in the area of combustion and pyrolysis of hydrocarbon fuels. The interest in the subject stems mostly from environmental concerns on pollutant emission from combustion devices. The research activities span experimental, theoretical, and computational efforts and cover a ...
