| Research Abstract |
The generation method of non-equilibrium plasma by dielectric barrier discharge(DBD)in a supersonic flow was established. Excited nitrogen molecules and oxygen radicals, which were suitable for ignition and combustion enhancement, were detected by a spectroscopic measurement. The effects of applied voltage and frequency in discharge on the generation of non-equilibrium plasma were clarified and the electric energy for generation of the plasma was estimated. Moreover, efficient discharge conditions for radical generation were theoretically supposed.
