Special Issue Information

Dear Colleagues,

Flame radiation is generally recognized as an important and fundamental subject in fire research (such as the hydrocarbon pool fire, compartment fire, jet flame, and so on) and many combustion systems. For example, flame radiation can exert a strong influence on fire detection, ignition, and spread, and indeed, flame radiation constitutes over 80% of the energy required for fuel gasification in large-scale fires. Accurate prediction of flame radiation requires a good understanding of the radiative transport theory as well as detailed information on the radiative properties of the combustion products. Flame radiation is essential for predicting their thermal performance as well as consequently improving the fuel economy.

The Special Issue aims to seek novel papers that address important issues related to flame radiation. The scope of this Special Issue is to gather original, fundamental, and applied research concerning experimental, theoretical, computational, and case studies that contribute towards the understanding of flame radiation. Original research articles and reviews are welcome. Topics of interest for publication include, but are not limited to, the following:

  • Heat flux and radiation characteristics inside compartment fire;
  • Thermal radiation from large hydrocarbon pool fire;
  • Heat radiation profiles of the window-ejected fire plume;
  • Flame behaviors in combustion;
  • Facade flame spread;
  • Flame morphology and radiation properties of jet fire;
  • Flame radiation properties under wind condition;
  • Heat radiation characteristics of corridor fire;
  • Combustion instability;
  • Case study of fire accidents;
  • Applications of the flame radiation.

We look forward to receiving your contributions.

Accidental hydrogen releases from pipelines pose significant risks, particularly with the expanding deployment of hydrogen infrastructure. Despite this, there has been a lack of thorough investigation into hydrogen leakage from pipelines, especially under complex real-world conditions. This study addresses this gap by modeling hydrogen gas dispersion, jet fires, and explosions based on practical scenarios. Various factors influencing accident consequences, such as leak hole size, wind speed, wind direction, and trench presence, were systematically examined. The findings reveal that both hydrogen dispersion distance and jet flame thermal radiation distance increase with leak hole size and wind speed. Specifically, the longest dispersion and radiation distances occur when the wind direction aligns with the trench, which is 110 m where the hydrogen concentration is 4% and 76 m where the radiation is 15.8 kW/m2 in the case of a 325 mm leak hole and wind under 10 m/s. Meanwhile, pipelines lacking trenching exhibit the shortest distances, 0.17 m and 0.98 m, at a hydrogen concentration of 4% and 15.8 kW/m2 radiation with a leak hole size of 3.25 mm and no wind. Moreover, under relatively higher wind speeds, hydrogen concentration stratification occurs. Notably, the low congestion surrounding the pipeline results in an explosion overpressure too low to cause damage; namely, the highest overpressure is 8 kPa but this lasts less than 0.2 s. This comprehensive numerical study of hydrogen pipeline leakage offers valuable quantitative insights, serving as a vital reference for facility siting and design considerations to eliminate the risk of fire incidents.
