A new LES model coupling flame surface density and tabulated kinetics approaches to investigate knock and pre-ignition in piston engines

Downsizing currently appears as a promising technique for reducing the CO 2 emissions of spark-ignition engines. Nevertheless boost levels are limited by the occurrence of uncontrolled auto-ignitions of fresh gases. These latter are sporadic and can have localized origins. The large-eddy simulation...
