Numerical Study of Flame Lift-off and Soot Formation in Diesel Fuel Jets
A detailed chemistry-based CFD model was developed to simulate the diesel spray combustion and emission process. A reaction mechanism of n-heptane is coupled with a reduced NOx mechanism to simulate diesel fuel oxidation and NOx formation. The soot emission process is simulated by a phenomenological soot model that uses a competing formation and oxidation rate formulation. The model is applied ...
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 کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Flame Experiments at the Advanced Light Source: New Insights into Soot Formation Processes
The following experimental protocols and the accompanying video are concerned with the flame experiments that are performed at the Chemical Dynamics Beamline of the Advanced Light Source (ALS) of the Lawrence Berkeley National Laboratory(1-4). This video demonstrates how the complex chemical structures of laboratory-based model flames are analyzed using flame-sampling mass spectrometry with tun...
متن کاملNew insight into the soot nanoparticles in a candle flame.
Using anodic aluminium oxide films as collectors, all four well known carbon forms, diamond, graphitic, fullerenic and amorphous particles, are identified inside a candle flame, suggesting a new nucleation mechanism for diamond growth and fullerene formation in a combustion synthesizing process.
