Recent advances in automation of systematically reduced mechanisms are reported here with the aim to accelerate the development process. A computer algorithm has been developed enabling fast generation and testing of reduced chemistry. This algorithm has been used to develop various reduced mechanisms of methane-air combustion for modelling of turbulent combustion. A 10-step reduced chemistry h...

Abstract The rotating detonation characteristics of high-temperature hydrogen-rich gas were studied. Hydrogen-rich was generated by the pre-combustion hydrogen, and a experiment air subsequently performed. auto-initiation observed in experiment, influence pre-detonation tube ignition on steady propagation wave analyzed. results show that have ability to spontaneously form waves. operation has s...

To date, high resolution spray-assisted dual-fuel (DF) studies have focused on capturing the ignition process while subsequent post-ignition events been largely neglected due to modeling requirements and computational cost. Here, we use a simplified approach for studying front evolution after ignition. Three-dimensional scale-resolved simulations of igniting shear layers (0≤Re≤1500) are studied...

The accidental ignition of combustible atmospheres by hot surfaces is great concern for chemical and process plant safety. In this paper, we present our research regarding the evolution thermal plumes originating from hemispheres discs. particular, focus on effect orientation surface process. auto-ignition temperatures locations were studied experimentally. To get further insight, conducted det...

the hcci combustion process is initiated due to auto-ignition of fuel/air mixture which is dominated by chemical kinetics and therefore fuel composition has a significant effect on engine operation and a detailed reaction mechanism is essential to analysis hcci combustion. a single zone-model permits to have a detailed chemical kinetics modeling for practical fuels. in this study a single-zone ...

Turbulent jet ignition technology can significantly improve lean combustion stability and suppress engine knocking. However, the narrow channel between pre-chamber main chamber leads to some difficulties in heat exchange, which affects performance mechanical component lifetime. To clarify effect of temperature conditions on evolutions turbulent ignition, direct numerical simulations with detail...
