Optimizing the internal design of a miniaturized fluidic oscillator for active flow control over a scaled NACA-4412

Résumé

The detachment of the boundary layer over the wing of an aircraft and its detrimental effects during the critical phases of the flight (mainly takeoff and landing) has been extensively studied [1]. Controlling the separation of the boundary layer decreases the energy consumption (and consequently CO2 emissions) while also improving the maneuvering capability, safety, and durability of the aircraft by suppressing instabilities. Active flow control by means of pulsed jets along the span of the wing can be used to compensate for the momentum deficit in the boundary layer to delay its detachment from the airfoil [2]. However, implementing active flow control devices leading to a net gain in the energy balance remains an open issue which the CleanSky PERSEUS project attempts to address. The focus of the presented work is on the design of the Pulsed Jet Actuators and the optimization of their internal geometry to provide a targeted performance over a scaled NACA-4412 airfoil.
