The effect of low barometric pressure and oxygen-enriched atmosphere on flame propagation speed over the thin material
The phenomenon of flame propagation over thin materials under low barometric pressures and oxygen-enriched atmospheres were studied experimentally. The experimental results show that when the barometric pressure is held constant,the greater the oxygen concentration is, the faster the flames propagate ; when the oxygen concentration is constant, the flame propagation speed increases with the increase of the barometric pressure; the flame propagation speed decreases significantly with the increase of barometric pressure under a constant partial pressure of oxygen. When the oxygen volume fractions were 20.9％ and 23％ at 101.3 kPa, the flame propagation speed were 2.47mm/s and 3.01mm/s respectively. According to which we obtained the corresponding oxygen volume fractions in different barometric pressures.
