Bi-directional probes are utilized throughout fire science to measure fire-induced flows due to their ability to measure flow which changes direction, and to withstand hostile environments. However, they are not available commercially and r...
Molecular content of nascent soot: Family characterization using two-step laser desorption laser ionization mass spectrometry [0.03%]
新型碳黑的分子组成:利用两步激光解吸激光电离质谱进行官能团表征

The flammability of combustible materials in spacecraft environments is of importance for fire safety applications because the environmental conditions can greatly differ from those on earth, and a fire in a spacecraft could be catastrophic...
Numerical study of gas-phase interactions of phosphorus compounds with co-flow diffusion flames [0.03%]

Firebrands are a significant source leading to structures ignited and lost in large outdoor fires, such as Wildland-Urban Interface (WUI) fires, a large international problem, and urban fires, common in Japan. Sadly, hardly any information ...
Effects of stretch and thermal radiation on difluoromethane/air burning velocity measurements in constant volume spherically expanding flames [0.03%]

Compared to current refrigerants, next-generation refrigerants are more environmentally benign but more flammable. The laminar burning velocity is being used by industry as a metric to screen refrigerants for fire risk, and it is also used ...
Soot, organics, and ultrafine ash from air- and oxy-fired coal combustion [0.03%]
