Book excerpt: An investigation of soot formation in laminar diffusion flames showed that soot particle surface growth under laminar diffusion flame conditions ceases because of the depletion of hydrocarbon species and not soot particle reactivity loss due to thermal aging of the particles. This result was obtained through direct species concentration measurements under well-controlled conditions, while the particle reactivity effects were calculated based on premixed flame results along with particle temperature/time information available from earlier laminar diffusion flame studies. Comparisons with a soot formation model which incorporated detailed chemistry effects showed good agreement in terms of predicted and measured species concentration and soot particle field evolution. In addition, a novel technique for measuring soot volume fraction was developed based on laser-induced incandescence and was successfully applied to similar laminar diffusion flame studies. This technique was extended to droplet and turbulent diffusion flame conditions where a two-dimensional imaging approach was employed to measure soot volume fraction. Finally, the complete data set from these studies was assembled in a form suitable for dissemination on computer diskettes throughout the research community for comparison with modeling efforts.

(Decio Santos) Bento and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2005 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laminar axisymmetric propane air diffusion flames were studied at pressures 0.1 to 0.725 MPa (1 to 7.25 atm). To investigate the effect of pressure on soot formation, radially resolved soot temperatures and soot volume fractions were deduced from soot radiation emission scans collected at various pressures using spectral soot emission (SSE). Overall flame stability was quite good as judged by the naked eye. Flame heights varied by 15% and flame axial diameters decreased by 30% over the entire pressure range.Analysis of temperature sensitivity to variations in E lambda(m) revealed that a change in E lambda(m) of +/-20% produced a change in local temperature values of about 75 to 100 K or about 5%.Temperatures decreased and soot concentration increased with increased pressure. More specifically, the peak soot volume fraction showed a power law dependence, fv ∝ Pn where n = 2.0 over the entire pressure range. The maximum integrated soot volume fraction also showed a power law relationship with pressure, f ̄v ∝ Pn where n = 3.4 for 1 ≤ P ≤ 2 atm and n = 1.4 for 2 ≤ P ≤ 7.25 atm. The percentage of fuel carbon converted to soot increased with pressure at a rate, etas ∝ Pn where n = 3.3 and n = 1.1 for 1 ≤ P ≤ 2 atm and 2 ≤ P ≤ 7.25 atm respectively.

This book was released on 1990 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies emphasizing the effects of fuel concentration and operating pressure on the formation of soot particles have been conducted in a series of laminar diffusion flames. These experiments have shown that fuel concentration has a measurable effect on the amount of soot formed in the flame. However, a simple, constant proportionality between the fuel concentration and soot volume fraction has not been found to apply for the range of flow conditions studied. This observation is believed to be a result of flame residence time and diffusion effects which mitigate the consequences of reduced initial fuel concentration. Comparisons with simple laminar diffusion flame models are currently being used to investigate the relationship between initial fuel concentration and local flame concentration fields. Similar studies of soot formation in laminar diffusion flames as a function of operating pressure have also been completed for ethene, ethane and propene fuel species. Keywords: Soot formation, Soot particles, Diffusion flames. (JES).

Available in PDF, EPUB and Kindle. Book excerpt: Soot volume fraction (f[subscript sv]) is measured quantitatively in a laminar diffusion flame at elevated pressures up to 25 atmospheres as a function of fuel type in order to gain a better understanding of the effects of pressure on the soot formation process. Methane and ethylene are used as fuels; methane is chosen since it is the simplest hydrocarbon while ethylene represents a larger hydrocarbon with a higher propensity to soot. Soot continues to be of interest because it is a sensitive indicator of the interactions between combustion chemistry and fluid mechanics and a known pollutant. To examine the effects of increased pressure on soot formation, Laser Induced Incandescence (LII) is used to obtain the desired temporally and spatially resolved, instantaneous f[subscript sv] measurements as the pressure is incrementally increased up to 25 atmospheres. The effects of pressure on the physical characteristics of the flame are also observed. A laser light extinction method that accounts for signal trapping and laser attenuation is used for calibration that results in quantitative results. The local peak f[subscript sv] is found to scale with pressure as p[superscript 1.2] for methane and p[superscript 1.7] for ethylene.
