Abstract EN
An efficient multigrid (MG) model was implemented for spark-ignited (SI) engine combustion modeling using detailed chemistry.
The model is designed to be coupled with a level-set-G-equation model for flame propagation (GAMUT combustion model) for highly efficient engine simulation.
The model was explored for a gasoline direct-injection SI engine with knocking combustion.
The numerical results using the MG model were compared with the results of the original GAMUT combustion model.
A simpler one-zone MG model was found to be unable to reproduce the results of the original GAMUT model.
However, a two-zone MG model, which treats the burned and unburned regions separately, was found to provide much better accuracy and efficiency than the one-zone MG model.
Without loss in accuracy, an order of magnitude speedup was achieved in terms of CPU and wall times.
To reproduce the results of the original GAMUT combustion model, either a low searching level or a procedure to exclude high-temperature computational cells from the grouping should be applied to the unburned region, which was found to be more sensitive to the combustion model details.
