Premixed flame ignition is a fundamental issue in combustion. A basic understanding of this
phenomenon is crucial for fire safety control and for the development of advanced …

Many countries consider hydrogen as a promising energy source to resolve the energy
challenges over the global climate change. However, the potential of hydrogen explosions …

In this research, the effect of ignition, initial pressure (50–250 kPa) and temperature (20–
100° C) on the lower flammability limit (LFL) of hydrogen/air mixture are investigated …

A micro combustor inserted with a bluff body ball was developed and compared with the
conventional combustor. The combustion characteristics (flammability limits, stable flame …

To understand the turbulence-chemistry interaction of lean hydrogen-air premixed flames at
elevated pressures, we conduct a series of high-fidelity direct numerical simulations with …

The conventional flame stretch analysis showed some technical limitations in describing the
observed extinction mechanism without considering the heat transfer characteristics related …

The paper discusses the peculiarities of flame propagation in the ultra-lean hydrogen-air
mixture. Numerical analysis of the problem shows the possibility of the stable self-sustained …

Despite rapid improvements in the performance of the central processing unit (CPU), the
calculation cost of simulating chemically reacting flow using CFD remains infeasible in many …

Direct numerical simulations were conducted to investigate the effect of two parameters,
density ratio and laminar flame speed, on the conditions of the onset of local extinction and …

As fossil fuels currently account for approximately 85% of the world's energy demands, the
rapid growth of the global population and the economy is projected to increase greenhouse …
