As an important dynamic quantity affecting the mean flow in the turbulent flow, the Reynolds stress greatly affects the momentum transfer in turbulent flows, and thus strongly influences the skin friction. Therefore, it plays a key role in friction drag and flow separation. The purpose of this article is to present the flow control with specially designed right-angle-shaped plasma actuator, which can emit jet at about 45° to manipulate the Reynolds stress and meanwhile to alter the reattachment location in the backward-facing step flow. In the experiment, the plused frequencies of the right-angle-shaped plasma actuator are modulated by the natural instability frequency at 0.5H (H means step height) streamwise position of the backward-facing step flow. The region from 0 to 2.5H is measured by particle image velocimetry (PIV), and the reattachment zone is also measured by PIV. The results show that when the right-angle-shaped plasma actuator is turned on, the maximum of Reynolds stress components in the region centered on the shear layer and near the shear layer are significantly increased by about 42% (Horizontal normal stress), by 75% (Vertical normal stress), and by 46% (Reynolds shear stress), and the maximum of the turbulent kinetic energy production in the region centered on the shear layer is reduced by about 35%.The reattachment location is moved upstream in the reattachment zone.
