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 …

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

The study presents the laminar methane-air non-premixed flame patterns under the
synergistic effect of heat and flow recirculation in a radial microchannel, as obtained through …

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 …

The manner in which an ultra-lean hydrogen flame stabilizes and blows off is crucial for the
understanding and design of safe and efficient combustion devices. In this study, we use …

The released hydrogen can be ignited even with weak ignition sources. This emphasizes
the importance of the hydrogen flammability evaluation to prevent catastrophic failure in …

To evaluate the effect of the disturbance airflow on the methane deflagration flame, a
deflagration experiment is conducted in a closed duct. The effects of three disturbance …

Lean limit flames of H 2-CH 4-air mixtures stabilized inside a tube with an inner diameter of
30 mm in a downward flow are studied experimentally and numerically. A transition from …
