Abstract:
The ignition of a dilute methane–oxygen mixture (total pressure, to 200 Torr) after a single obstacle can be observed markedly far from the obstacle surface. The use of meshed sphere as an obstacle leads to an increase in the distance of flame emergence behind the obstacle in comparison with a round opening; two or more close-meshed obstacles strongly suppress flame propagation.
