ABSTRAKT

This work extends the investigation by Goryntsev et al. (2007) of cycle-to-cycle variations of flow and mixing field using Large Eddy Simulation (LES) method to fuel spray injection driven flows using the CFD KIVA-3V code (Amsden et al., 1989) as extended to LES. Especially the effect of the cycle-to-cycle variations on the fuel-air-mixing close to the ignition point will be investigated. The configuration investigated represents the "BMBF" generic four-stroke direct fuel injection engine with variable charge motion system. Some experimental data for single phase flow and spray are available. They will be used for model validation.
