It has been shown that the actuator can generated so-called vortex train if it is powered by modulated voltage waveform. Now, the plasma DBD actuator is placed inside a rectangular channel and an interaction with boundary layer (BL) is studied. The characteristics of the BL are modifying by varying inlet velocity. The actuator is adjusted to be set in spanwise orientation which means that the generated wall-jet-like flow is oriented in the same meaning as the main flow or in the opposite direction. The interaction of vortical structures generated by actuator with BL will be described quantitatively from mean flow field.
