“…The corresponding databases have provided a stronghold for engine simulations with regards to model validation and development. Together, experimental and (RANS-) modeling studies have jointly addressed studies of flow cycle-to-cycle variations (ccv) [14,23], sprays [15], ignition [24][25][26], and combustion [27]. Large Eddy Simulation (LES) studies have primarily been concentrated with the SGEmac, Darmstadt, and TCC-III engine databases.…”

This work shows experiments and simulations of the fired operation of a spark ignition engine with port-fueled injection. The test-rig considered is an optically accessible single cylinder engine specifically designed at TU Darmstadt for the detailed investigation of in-cylinder processes and model validation. The engine was operated under lean conditions using isooctane as a substitute for gasoline. Experiments have been conducted to provide a sound database of the combustion process. A planar flame imaging technique has been applied within the swirl and tumble plane to provide statistical information on the combustion process to complement the pressure-based comparison between simulation and experiments. This data is then analyzed and used to assess the Large Eddy Simulation performed within this work. For the simulation, the engine code KIVA has been extended by the dynamically thickened flame model combined with chemistry reduction by means of pressure dependent tabulation. 60 cycles have been simulated to perform a statistical evaluation. Based on a detailed comparison with the experimental data, a systematic study has been conducted to obtain insight into the most crucial modeling uncertainties.

“…Forced ignition modeling is not new, as numerous studies have focused on forced ignition in internal combustion engines [19][20][21][22][23]. However, few have considered spark ignition of nonpremixed burners [24][25][26], mainly because these burners, like those found in gas turbines, operate in combustion regimes that are, overall, steady.…”

“…In [31] and [32], FSD transport equation based ignition models have been developed considering aforementioned aspects. Recently, an experimentally based comprehensive formulation combined with the G-equation approach has also been proposed in [33] and [34] for RANS simulations. This would, probably be easily extended in to LES, in a LES G-equation formulation.…”
