| Research Abstract |
Jet diffusion control was performed by giving induced flow of dielectric barrier discharge to the jet exit. Centripetal type and coaxial type were used as the electrode. The following findings were obtained. The centripetal type electrode, Increase of the voltage enhances the flow contraction effect, and Increase of the frequency expands the diffusion effect. The coaxial type electrode, it is possible diffusion effect is enhanced by the instability is enhanced, collapse and the formation of vortex rings occurs early and to shorten the diffusion jet.
