Interaction of the laminar flames of methane-air mixtures with close-meshed spherical and planar obstacles in a closed cylindrical reactor under spark discharge initiation
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 mm$^2$ 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.
