Abstract
The dielectric barrier discharge plasma actuator (DBD PA) is applied to diffusion control of the jet flow issued at Reynolds numbers (based on a nozzle diameter) of Re = 1.0 × 103 and 2.0 × 103 from a nozzle of 10 mm in diameter. The detailed flow structure is documented using particle image velocimetry, hot-wire anemometry, and laser flow visualization. In the experiment of the present study, the jet flow was controlled using a coaxial DBD PA, which generates an induced flow in the same direction as the jet direction. We investigated the difference in the influence of the flow induced by DBD PA on the main jet flow while varying the voltage, frequency, and intermittency. The induced flow was found to become stronger as the frequency and voltage increased. The diffusion of the jet flow was controlled.
