Influence of the initiation energy on development of hydrogen–air mixtures combustion in large spherical volumes

We investigate the influence of the initiation energy on the development of burning in hydrogen–air mixtures with an hydrogen content of 7–31% (volume). We initiated the mixtures in the center of the spherical reaction volume, 7–40 m 3 in size, by energies from 1 J up to 4600 J. The reaction volume...

Description
Summary:We investigate the influence of the initiation energy on the development of burning in hydrogen–air mixtures with an hydrogen content of 7–31% (volume). We initiated the mixtures in the center of the spherical reaction volume, 7–40 m 3 in size, by energies from 1 J up to 4600 J. The reaction volume was bordered by a thin rubber envelope and located inside the 910 m 3 spherical explosion chamber. We registered the flame front movement by means of the ionization sensors, the video camera, and the high-speed video camera.
