Three-Dimensional Modeling of Combustion Process, Soot and NOx formation In a Direct-injection Diesel Engine
This paper is presented to study the combustion process and emissions in a direct injection diesel engine. Computations are carried out using a three-dimensional model for flows, sprays, combustion and emissions in Diesel engines. Interactions between combustion and emissions with flow field are considered and it is shown that soot mass fraction increases at regions with low turbulence inten...
متن کاملEffect of High Injection Pressure on Mixture Formation, Burning Process and Combustion Characteristics in Diesel Combustion
The mixture formation prior to the ignition process plays as a key element in the diesel combustion. Parametric studies of mixture formation and ignition process in various injection parameter has received considerable attention in potential for reducing emissions. Purpose of this study is to clarify the effects of injection pressure on mixture formation and ignition especially during ignition ...
متن کاملSoot Formation within Conventional and Low Temperature Diesel Combustion
The soot formation processes of conventional and low temperature diesel combustion were investigated by a newly developed Forward Illumination Light Extinction (FILE) soot measurement technique in a constant volume spray chamber. The FILE technique has the capability to obtain two-dimensional time-resolved quantitative soot measurements. For diesel combustion at conventional ambient condition, ...
متن کاملOn the Dependence of Soot Formation and Combustion on Swirling Combustion Furnaces: Measurement and Simulation
Soot concentration distribution is investigated both numerically and experimentally in methane-air diffusion flame. The experimental work is conducted with a cylindrical swirl stabilized combustor. Filter paper technique is used to measure soot volume fraction inside the combustor. The numerical simulation is based on the solution of the fully-coupled conservation equations for swirling turbule...
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. ...
