Various fluidic oscillators were tested on a model of the NASA hump geometry in support of the development of active flow control technology. Time-averaged pressure measurements were conducted with high spatial resolution along both the chord and span of the model. Well-established flow control coefficients (based on momentum and energy) are used as criteria to compare the performance and efficiency of different fluidic oscillator designs. Additionally, Stereoscopic Particle Image Velocimetry and surface flow visualization were employed to provide insight on the flow physics. Results indicate large deviations in efficiency for different actuator geometries. This is in part due to different opening angles of the jets and the associated spanwise coverage. The strength and coherence of counter-rotating vortex pairs along the span significantly influences the performance but is not a universal indicator of control authority.
