A numerical simulation was performed for a 2D plasma flow control of flow around a circular cylinder at Reynolds number 6.6e3.

The plasma actuator model proposed by Suzen et al. was used. Poisson equations for the electric potential and the charge density were solved to compute the body force field. The body force generated by the plasma actuator model was incorporated into the flow solver as source terms for the momentum equations.

The simulation with plasma actuators demonstrated a smaller wake and reduced vortex shedding behind the cylinder compared to the reference case without the actuators. The influence of the locations of the plasma actuators was investigated with a parametric study. The results indicate that the effectiveness of the plasma actuation is sensitive to the actuator locations.
