Abstract:
The wide range of diesel engine operating conditions demand for a robust combustion model to account for inherent changes. In this work, the Flamelet Generate Manifold (FGM) approach is applied, in STAR-CD framework, to simulate the conventional injection- and early injection-timing (PCCI like) combustion regimes. Igniting Counter flow Diffusion Flamelets (ICDFs) and Homogeneous Reactors (HRs) are used to tabulate chemistry for conventional and PCCI combustion modes, respectively. The validation of the models with experimental data shows that the above consideration of chemistry tabulation results in accurate ignition delay predictions. The study reveals that a moderate amount of 5 different pressure levels is necessary to include in the FGM database to capture the ignition delay in both combustion regimes.
