Suppression of deflagration flame propagation of methane-air in tube by argon gas and explosion-eliminating chamber [PDF]

Scientific Reports, 2022
To explore the inhibitory effect of argon gas and explosion-eliminating chamber on methane-air deflagration flame propagation in the tube, based on the Φ = 120 mm, L = 5.5 m stainless steel pipeline test system to measure methane-air deflagration flame ...

Cool Flame Propagation Speeds

Combustion Science and Technology, 2007
Cool flames are studied at reduced-gravity in a closed, unstirred, spherical reactor to minimize complexities associated with natural convection. Under such conditions, transport is controlled by diffusive fluxes and the flames are observed to propagate ...

Direct determination of burning velocity during aluminium flame propagation

Chemical Engineering Transactions, 2022
Numerical simulations are needed to model accurately the consequences of dust explosions. One key parameter for modelling the flame propagation is the burning velocity (ie the consumption rate of the reactants by the flame front).
