| Outline of Final Research Achievements |
Induced flow of a dielectric barrier discharge is applied to the jet outlet, diffusion control of the air jet and the carbon dioxide jet have been studied. Moreover, the behavior of the flame in the case of applying a plasma to the laminar flame were investigated.
In the air jet and the carbon dioxide jet, burst control promotes instability order to amplify the Preferred frequency, velocity potential core from that collapse at an early stage, the jet center velocity is attenuated at an early stage. Also, in the laminar flame experiments, under the condition of equivalence ratio: 0.80, blowout of the flame is suppressed upon application of a plasma. Furthermore, when a high voltage is applied, than the combustion acceleration effect due to the plasma increases the velocity in the near of the boundary layer due to induced flow of plasma actuators, flame shape becomes unstable, it tends to misfire.
