Sweeping Jet Actuator (SWJ), when pressurized with high pressure fluid, emit continuously but spatially oscillating jets, which are self-induced and self-sustaining. The initiation and interaction of the internal flow and jet oscillation process of a actuator is well defined in this study. Transient as well as steady numerical analysis over a range of inlet velocities was performed. The velocity magnitude and total pressure contours are shown to justify the complex flow field within the sweeping jet actuator by varying the height and width of the feedback channel geometry.
