Modeling of PCCI combustion with FGM tabulated chemistry

Since ignition control is difficult in the aforementioned combustion concept, the accurate prediction of ignition phenomena is significant. Simulations are performed with three different mesh settings, where the course grid proves to be sufficiently accurate. Later the effect of multiple pressure levels is investigated using both canonical systems and the study shows that a number of three pressure levels is sufficient to capture the ignition phasing with Homogeneous Reactors based FGM tables. Finally, the sensitivity of ignition with respect to injection timing is shown to be predicted precisely.
