Resumen:
We analysed the modifications of the near wake of a circular cylinder
(2,300< Re <58,000) when the flow was perturbed steadily using an
electrohydrodynamic actuator. Two electrodes flush-mounted on the surface of the
cylinder were excited with DC power supplies to create a plasma sheet contouring
the body. The discharge produced an electric force and changed the physical
properties in the fluid layers at close vicinity to the surface. This plasma
sheet diminished the base pressure, modified the size of the mean recirculation
region and produced an increase in the shear stresses of the layers bounding the
contour of this region
