Detailed chemistry flamelet modeling of mixed-mode combustion in spark-assisted HCCI engines

Evaluation of the flame propagation within an SI engine using flame imaging and LES

“…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.…”

“…Within these works chemistry is treated by reduced mechanisms. In order to account for detailed chemistry effects, also tabulation has already been applied to diesel engines [41,42], spark assisted HCCI-engines [27], and to treat the auto ignition of engine knock [40]. Regarding the configuration, most of these studies considered the single-cylinder optical SGEmac engine [19] operating with a propane-air mixture where the pressure curves were used as the assessment criteria.…”

A Comparative Study of Conditional Moment Closure Modelling for Ignition of iso-octane and n-heptane in Thermally Stratified Mixtures

“…The G-equation model combined with a multi-zone approach was applied to sparkassisted HCCI engines [23]. In this model, an extended form of the G-equation model was used for tracking the flame propagation whereas auto-ignition was captured by a multi-zone model.…”

Large Eddy Simulation of Premixed Combustion in Spark Ignited Engines Using a Dynamic Flame Surface Density Model

“…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.…”
