- •
A single DBD can delay to 64% of chord a turbulent flow that naturally separates at mid-chord of an airfoil at a Reynolds number equal to 1.3 × 106.
- •
The separation is delayed up to 80% when three DBD are used at a dimensioneless forcing frequency close to 0.3 and 3.
- •
The burst-modulation forcing is less effective than a standart forcing in the case of a turbulent boundary layer at high velocity.
