Abstract: 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.
