    LES Simulation of Direct Injection SI-Engine In-Cylinder Flow

  • Original language description

    The present paper deals with the application of the LES approach to in-cylinder flow modeling. The main target is to study cycle-tocycle variability (CCV) using 3D-CFD simulation. The engine model is based on a spark- ignited single-cylinder research engine. The results presented in this paper cover the motored regime aiming at analysis of the cycle-resolved local flow properties at the spark plug close to firing top dead center. The results presented in this paper suggest that the LES approach adoptedin the present study is working well and that it predicts CCV and that the qualitative trends are in-line with established knowledge of internal combustion engine (ICE) in-cylinder flow. The results are evaluated from a statistical point of view based oncalculations of many consecutive cycles (at least 10). Special attention is paid to local properties at the spark plug as these local conditions are supposed to strongly influence early phase of combustion process (early flame kernel dev
