Compressible reacting flows may display sharp spatial variation related to shocks, contact
discontinuities or reactive zones embedded within relatively smooth regions. The presence …

The ignition regime criteria proposed by Im et al.(2015) are extended to account for
temperature and concentration fluctuations. The newly-developed criteria are applied to …

The effects of turbulence on knock development and intensity for a thermally
inhomogeneous stoichiometric ethanol/air mixture at a representative end-gas autoignition …

Ammonia (NH 3) combustion is an attractive energy source with zero carbon dioxide (CO 2)
emissions and a potential hydrogen-combustion enabler. In addition, the availability of …

Detonation development inside spark ignition engines can result in the so called super-
knock with extremely high pressure oscillation above 200 atm. In this study, numerical …

The binary fuel blend of H 2/CH 4 is one of the most promising hydrogen-enriched
hydrocarbon fuels in spark-ignition (SI) engines. Yet, the undesirable phenomenon of super …

Theoretical framework and high-fidelity direct numerical simulations (DNS) on preignition
and knock encountered in internal combustion (IC) engines are briefly reviewed in this …

Front propagation speeds from fully resolved unsteady one dimensional simulations with
dimethyl-ether (DME)/methane (CH 4)/air mixtures under engine relevant conditions are …

Knocking limits the performance and efficiency of highly compressed, downsized spark
ignition combustion engines. In this paper, the effect of the first-stage ignition on knock is …

Advanced low-temperature-combustion (LTC) strategies of downsized and boosted engines
offer ultra-low emissions and higher efficiencies [1–8]. The combustion is chemically driven …
