Direct Injection Gasoline different numerical simulation models were analyzed. There are three kinds of the numerical simulation of turbulent: direct numerical simulation, large eddy simulation and Reynolds averaged simulation. Direct numerical simulation of turbulence modeling without using the numerical calculation solves the flow equations directly. Large eddy simulation of the main idea is: use...
To calculate soot source terms a new soot model is applied to study the formation and oxidation of soot particles in turbulent flames. The model is based on a detailed description of the chemical and physical processes leading to the formation of soot. It can be subdivided into the growth of polycyclic aromatic hydrocarbons (PAHs) in the gas phase reactions and the processes of particle inception,...
To calculate soot source KIVA-3V software is applied to study the formation and oxidation of soot particles in turbulent flames. The model is based on a detailed description of the chemical and physical processes leading to the formation of soot. It can be subdivided into the growth of polycyclic aromatic hydrocarbons (PAHs) in the gas phase reactions and the processes of particle inception, condensation,...
To analyze exactly the three-dimensional turbulent combustion temperature field in direct-Injection (DI) diesel engine modification in the CFD (computational fluid dynamics)-code (KIVA-3V) is performed. Three coordinate transformations are carried out to deduce temperature equations. The mixture fracture space is used for the first transformation. Multi-step chemistry reactions using steady state...
