Tandem cylinder flow control in the form of dielectric barrier discharge, DBD, plasma actuation on the upstream cylinder is used to control the wake and flow around the downstream cylinder. Twin spanwise-oriented plasma actuators are mounted at ± 80 degrees from the forward stagnation point of the upstream cylinder. The actuators are powered with two different AC voltage levels, low-power forcing and high-power forcing. Flow control experiments are performed at Reynolds number 4,700, and cylinder spacing range 3 > L/D > 5. Results include pressure measurements on the downstream cylinder and wake surveys using Particle Image Velocimetry, PIV. High-power forcing reduces the height between vorticity peaks behind upstream cylinder and, in the case of L=3D, restricts upstream wake from impinging on downstream cylinder.
