Numerical simulations of combustion in a lean stratified propane-air mixture
نویسندگان
چکیده
Direct numerical simulation (DNS) of combustion in globally lean non-homogeneous propane-air mixtures has been performed for several initial distributions of non-homogeneities. Results have shown a strong influence of the scale and asymmetry of this distribution on both the combustion efficiency and thermal NO production, in accordance with experimental results. The simulations also have made possible a quantitative assessment of flamelet modeling for the primary flame, which yielded remarkably good results.

A Study of EGR Stratification in an Engine Cylinder
One strategy to decrease the amount of oxides of nitrogen formed and emitted from certain combustion devices, such as the internal combustion engine, is to recirculate and introduce a portion of the unburned product gases with the air and fuel. The effect of the re-circulated gases is to decrease the maximum temperatures in the flame zone, and hence decrease NOx formation. However, dilution of ...
متن کاملNumerical Simulation of Combustion with Porous Medium in I.C. Engine
Porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. Advanced new generation of internal combustion (IC) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. These c...

متن کاملStudying the Effect of Reformer Gas and Exhaust Gas Recirculation on Homogeneous Charge Compression Ignition Engine Operation
Combustion in homogeneous charge compression ignition (HCCI) engine is controlled auto ignition of well-mixed fuel, air and residual gas. Since onset of HCCI combustion depends on the auto ignition of fuel/air mixture, there is no direct control on the start of combustion process. Therefore, HCCI combustion becomes unstable rather easily especially at lower and higher engine load. Charge strati...
