The control effect for the flow around a square cylinder using the DBD plasma actuator

Reynolds number : 33000
Surface velocity : 2.5 [m/s]
Duty ratio : 20 [%]
Location of the surface velocity : upstream corners of the cylinder
Blue tracer : Introduced when the actuator is off
Red tracer : Introduced when the actuator is on
Please check the reference for details.
Without control
Burst frequency : 50 [Hz]
Burst frequency : 100 [Hz]
Burst frequency : 400 [Hz]
