An experimental effort was performed in order to identify and quantify the structural changes to a two-dimensional turbulent boundary layer under the influence of a high spanwise aspect ratio slot synthetic jet. A comprehensive test matrix of key synthetic jet variables including non-dimensional stroke length, jet Reynolds number, and slot angle, was conducted in quiescent air, zero pressure gradient, and a mild adverse pressure gradient turbulent boundary layer flows. Time averaged and phase averaged features of the modified boundary layer flowfield were examined using hot-wire anemometry. Velocity profiles and turbulence data measured downstream of the actuator were compared for the range of actuator parameters with the baseline turbulent boundary layers.
