This paper synthesizes prior studies to develop a comprehensive three-dimensional description of reattached flow over an airfoil controlled by finite-span SJA arrays. When applied to a longer-span wing, the flow field exhibits three distinct regions:

This paper presents an experimental study on flow reattachment over a stalled airfoil using an array of microblowers operating as synthetic jet actuators (SJAs). The effects of burst duty cycle (DC) and blowing ratio, alongside power requirements, ar

An array of twelve circular-orifice synthetic jet actuators (SJAs) was used to provide the unsteady forcing required for flow separation control over a National Advisory Committee for Aeronautics (NACA) 0025 airfoil at a chord-based Reynolds number o

Three different circular synthetic jet modeling inlet conditions are studied for a turbulent crossflow. The study examines the differences when modeling the whole SJA, neck-only or jet-slot-only under constant actuation frequency (f = 300 Hz) and cro
