Available in PDF, EPUB and Kindle. Book excerpt: This investigation deals with a liquid fuel diffusion flame and examines the use of the smoke point test as a means of qualitatively measuring the ability of a fuel to produce soot relative to other fuels. Results indicate the necessity of controlling the initial conditions in order to obtain meaningful measurements. This thesis reports a new technique for the smoke point determination that has proved to be more accurate and reproduceable than previous methods. Recent studies indicate water addition in a premixed flame chemically suppresses soot formation. As a result, addition of water inside a diffusion flame is a likely direction to pursue. Both water in fuel emulsions and direct steam injection were used in the present investigation. The results indicate a dominant thermal effect and a possible secondary chemical effect of water on soot formation. Blending of various fuel types reveals the domination of an aromatic fuel over an aliphatic when determining a combined smoke point of the mixture. Applying this information to alternative hydrocarbon fuels, the oil shale and coal derived fuels, having a higher percentage of aromatics than conventional fuels, produce soot more readily than their petroleum derived counterparts. Testing of oil shale and conventional fuels supplied by the Air Force verifies this result.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present thesis, fundamental experimental and numerical studies are performed for the soot formation of liquid fuel relevant compounds. The thesis is composed of four research studies. The first develops an improved data analysis approach for the combined laser extinction and two-angle elastic light scattering diagnostics to relate the various measured optical cross sections to soot aggregate properties. Compared to previously reported studies, the proposed approach can be applied to a wider range of soot sources by removing the assumption made to scattering regime or moment ratio of aggregate size distribution. The second study investigates the effects of n-propylbenzene addition to n-dodecane on soot formation and aggregate structure in a laminar coflow diffusion flame using the combined laser extinction and two-angle elastic light scattering method. It is shown that the relative importance of soot inception and surface growth affected by n-propylbenzene addition is different along the flame wing and centerline, with the aromatic fuel chemistry effect being stronger along the centerline. The third study extends the investigation on the same issue using a numerical model. The simulation results show that mixing n-propylbenzene into the liquid fuel mixture accelerates soot inception, and increases soot surface growth per unit surface area by PAH addition, while soot surface growth per unit surface area by HACA is shown to decrease modestly with n-propylbenzene addition. The fourth and final study investigates the soot formation from jet fuel in a laminar coflow diffusion flame using both numerical and experimental methods. The results demonstrate the robustness of the soot model to changes of fuel and also show that the HyChem model (i.e., lumped fuel breakdown approach, Xu et al., 2017) can be used to predict soot formation from real jet fuel combustion in laminar coflow diffusion flames by adding a PAH growth scheme to the model.

Available in PDF, EPUB and Kindle. Book excerpt: Experiments in progress are described which have as their objective the clarification of the mechanisms responsible for soot suppression in flames by fuel additives. Measurements have been carried out in small well-defined diffusion flames for both gaseous and liquid fuels. Data have been obtained for selected organic and inorganic compounds of Ba, Fe, K and Mn as additives. The experimental techniques either employed or projected for use in the near term are in-situ by virtue of their reliance on nonperturbing laser-optical diagnostics. These techniques are Mie scattering, laser-induced fluorescence and coherent anti-Stokes Raman scattering to measure soot size and concentration, additive and other species concentrations and flame temperature, respectively. For gaseous fuels, inorganic salts of the above metals have been evaluated as additives in an ethylene/air flame. Additive suppression of soot was demonstrated, and particulate size, concentration and volume fraction were measured throughout the flame. Significantly, additive effectiveness varied with measurement position, and dissimilar metal behaved differently with respect to their alteration of soot parameters. In addition to particulate measurements, Ba additive chemical states in the flame have been identified from their optical emission spectra, and laser-induced fluorescence measurement has been demonstrated for a molecule closely identified with one of the latter states. For liquid fuels, ferrocene (dicyclopentadienyl iron) has been evaluated as an additive in wick and cylindrical counterflow diffusion flames. (Author).
