Abstract :
Nonthermal equilibrium plasma has been reported to be potentially applicable in many combustion scenarios. In this paper, the effects of dielectric barrier discharge (DBD) on the flame structure of a Bunsen flame have been investigated by using the OH planar laser-induced fluorescence technique. Results show that the increase of discharge intensity significantly enhances the local burning. In coaxial-cylinder DBD reactor, the flame structure can be varied from conic shape to M shape with discharge power increasing.
