متن کاملSuppression effects of diluents on laminar premixed hydrogen/oxygen/nitrogen flames
Laminar burning velocities and the flame response to stretch, as characterized by Markstein numbers, were determined experimentally and computationally for outwardly propagating spherical laminar premixed flames. The mixtures studied were premixed hydrogen/air/diluent and hydrogen/30% oxygen and 70% nitrogen (by volume)/diluent flames, with the latter condition of interest for pre-external vehi...
متن کاملChemically-Passive Suppression of Laminar Premixed Hydrogen Flames in Microgravity
Effects of chemically-passive fire suppressants on laminar premixed hydrogen flames were investigated by combined use of microgravity experiments and computations. The experiments used a short-drop free-fall laboratory facility that provides at least 450 ms of 2 10 g. Near -limit laminar burning velocities were measured for outwardly propagating spherical stoichiometric hydrogen-air flames with...
متن کاملStudy of Propane-air Flame Propagating in Narrow Channels under Quenching Condition
A new apparatus has been constructed to investigate the quenching of laminar hydrocarbon-air flames, at elevated initial pressures. The pressure-tight quenching channel is of trapezoidal form, with very smooth decrease of the channel width along its one meter length that is almost equivalent to a parallel-plate flame arrester. Propane-air mixture has been tested on the entire flammability domai...
متن کاملEffect of CH4–Air Ratios on Gas Explosion Flame Microstructure and Propagation Behaviors
To reveal the inner mechanism of gas explosion dynamic behavior affected by gas equivalent concentration, a high speed Schlieren image system and flow field measurement technology was applied to record the gas explosion flame propagation and flame structure transition. The results show that a flame front structure transition occurs, followed by a flame accelerating propagation process. The lami...
