Examination of the Flame Transmission through Porous Structures
S. Mecke, D. Markus, C. Scholz, M. Thedens, H.D. Kim, F. Engelmann, A. Hilliger and U. Klausmeyer

Porous structures can be used to avoid flame transmissions as it is done in flame arresters or breathing devices of explosion protected equipment. A detailed examination of the different flame transmission behaviours of different porous structures is performed using several methods of laser diagnostics. The flow behaviour is analysed using a Schlieren technique and the flame transmission itself is examined using laser induced fluorescence of OH radicals.

Keywords: Flame arresters, flame transmission, quenching, porous structure, OH LIF, explosion.
