the present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. soot concentrations inside the combustor are measured by filter paper technique. the simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and soo...

aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (al(no3)3.9h2o) and ammonium sulfate ((nh4)2so4). the resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. the crystallinity and phase of  the as-synthesized and calcined samples were characteri...

Tungsten oxide (WO3) and tungsten oxide hydrate (WO3.H2O) nanoparticles were synthesized via microwave-assisted solution combustion in comparison with the acidic precipitation method. Oxalic acid was used as a surfactant and forming agent in the acidic precipitation method. In addition to oxalic acid, glycine and citric acid were also used as fuels in the microw...

In the present study, potassium chloride-assisted solution combustion method was used to synthesize cobalt ferrite nanoparticles. Potassium chloride salt as a specific surface enhancer and nitric acid an auxiliary oxidizer pH regulator. The simultaneous effect of initial amount added on area, structural, microstructural magnetic properties synthetic powders were studied. X-ray Diffraction (XRD)...

Van Slyke and Folch (1) used as a combustion mixture a solution of H&04, HsP04, and CrOa, to which pulverized KI03 was added in the combustion tube. It has been found advantageous instead to use as a fluid a mixture of H&S04 and HsPOa without CrOs, both KI03 and KzCrzOr being added in solid form in the combustion tube. This modification has the advantage that both the liquid and the solid reage...

We consider a diffusional-thermal model with twostep competitive reactions for premixed combustion wave propagation in one spatial dimension. Numerical investigation of the flame speed of the system for different fuel types shows the existence of regions where two stable travelling combustion wave solutions co-exist solutions pertaining to the fast and slow branches. A hysteresis type phenomena...

The combustion of fossil fuels forms polycyclic aromatic hydrocarbons (PAHs) composed of five- and six- membered aromatic rings, such as indene (C9 H8 ), which are carcinogenic, mutagenic, and deleterious to the environment. Indene, the simplest PAH with single five- and six-membered rings, has been predicted theoretically to be formed through the reaction of benzyl radicals with acetylene. Ben...
