Abstract
An AC single plasma actuator has been developed using a magnetic fluid (MF) and a dielectric barrier discharge (DBD), termed ``single MF-DBD plasma actuator''. In this system, the DBD induces an ionic wind from the MF, which is held in place by an external magnetic field. This study investigates the effect of an external magnetic field on the ionic wind velocity. The experimental results indicated that the external magnetic field effectively controls the ionic wind velocity due to the interaction between the MF and the exposed electrode. The efficiency of the ionic wind generation is also analyzed and clarified. Tables 1, Figs 10, Refs 9.
