“…Differences in heat release rate structure are also seen at the 90% heat release point where cases a-2D and b-2D burn in thin reaction fronts whereas case c-2D burns more or less homogeneously. These findings are consistent with hydrogen/air results reported in Bansal and Im [21] where the uncorrelated T À / case was also found to burn in the thin reaction front regime and the negatively correlated T À / case was found to burn more homogeneously. It is interesting to note that these observations persist even in hydrocarbon fuels such as DME.…”

“…As discussed in Ref. [21], matching the turbulence integral time scale and T 0 leads to temperature gradients which are comparable in DNS and real engines. This is the case even though the initial length scales of inhomogeneities ðL 11;T Þ are much larger in real engines than those specified in the present DNS study.…”

“…The effect of thermal stratification under HCCI conditions has been investigated using direct numerical simulation (DNS) for various fuels such as hydrogen [8][9][10][11], n-heptane [12,13], iso-octane [14] and dimethyl ether [15,16]. From some of these DNS studies, two combustion modes were found under HCCI conditions: deflagration and spontaneous ignition.…”
