“…This effectively demonstrates the principal role of radiation heat transfer in combustion growth for high-temperature metals. As a means of quantifying this concept, Christophe et al designed an experimental setup to effectively measure the radiated flux during flame propagation through aluminum/air mixtures (particle size = 100 μm, fuel concentration = 270 g/m 3 , radiated flux = 40 kW/m 2 ) …”

“…In a series of qualitative studies by Leuschke, the significance of radiation heat transfer within metal dust clouds was confirmed. 38 39 Other groups have investigated this topic from a theoretical, numerical solution perspective. Utilizing a discrete element method (DEM), investigations by Moussa et al successfully simulate the radiative heat transfer between dust cloud particulates as well as the heat transfer which occurs in the bulk preheat zone.…”

Metal dust deflagrations continue to pose a critical threat toward safety in the metal processing industry. This paper begins with introduction of the fundamental requirements for an explosion and reviews the modern developments in explosion prevention techniques, while describing the challenges confronted with applying these techniques to nonstandard metal dust applications. Variability in several intrinsic properties associated with bulk solids conveyance (such as propagation behavior, degree of turbulence, particle size, and moisture content) contributes to metallic fuels having the increased potential to act as highly reactive explosion hazards. Upon ignition in a contained enclosure volume and propagation to interconnected vessels, metal dusts exhibit augmented explosion severity and sensitivity because of their large heats of combustion, higher burning temperatures, radiative heat transfer effects, and abnormally reactive interactions with water. These characteristics are specific to metal dust fuels and are not commonly demonstrated in organic combustion.
