Abstract
The spark initiated flames of dilute stoichiometric natural gas–oxygen mixtures in close-meshed aluminum spheres with a mesh size of 0.1–0.2 mm2 do not propagate through the spheres but always propagate through planar meshed obstacles of the same mesh size. It is found that the features of flame propagation under simultaneous initiation at the opposite butt-ends of a cylindrical reactor differ markedly from those under initiation from a single discharge.
