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 کاملComputational and Experimental Study of Soot Formation in a Coflow, Laminar Ethylene Diffusion Flame
A sooting, ethylene coflow diffusion flame has been studied both experimentally and computationally. The fuel is diluted with nitrogen and the flame is slightly lifted to minimize the effects of the burner. Both probe (thermocouple and gas-sampling techniques) and optical diagnostic methods (Rayleigh scattering and laser-induced incandescence) are used to measure the temperature, gas species, a...
متن کاملInteractions between soot and CH in a laminar boundary layer type diffusion flame in microgravity
A three-dimensional laminar non-buoyant diffusion flame was studied with the objective of improving the understanding of the soot production. The flame originated from a porous ethylene burner discharging into a laminar boundary layer. Soot volume fractions were measured using Laser-Induced Incandescence (LII) and the spontaneous emission from CH∗ was determined using chemiluminescence. The mai...
متن کاملSoot Formation and Oxidation in Laminar Flames (Invited)
The flame and soot structure, including soot primary particle nucleation, surface growth and oxidation properties, of 6 premixed and 20 diffusion flames were studied experimentally for various fuels, at temperatures of 1400-2350 K and at pressures of 13-811 kPa (0.1-8.0 atm). Measurements were made along the axes of flames with the reactants at normal temperature (300 K). The following properti...
متن کاملMeasurement of the spatially distributed temperature and soot loadings in a laminar diffusion flame using a Cone-Beam Tomography technique
A new low-cost optical diagnostic technique, called Cone Beam Tomographic Three Colour Spectrometry (CBT-TCS), has been developed to measure the planar distributions of temperature, soot particle size, and soot volume fraction in a co-flow axi-symmetric laminar diffusion flame. The image of a flame is recorded by a colour camera, and then by using colour interpolation and applying a cone beam t...
