Numerical simulation of the flow around a square cylinder under plasma actuator control

Zihao Zhu et al.

Summary: Navier-Stokes computations were used to study the effects of dielectric barrier discharge (DBD) plasma actuators on flow past a square cylinder. It was found that the effectiveness of flow control by the plasma actuators varied with the location and input power of the actuators in different configurations. The best flow control effect was achieved in the last configuration where vortex shedding and drag were significantly reduced.

Effect of dielectric barrier discharge plasma actuator on the dynamic moment behavior of pitching airfoil at low Reynolds number

Guangjing Huang et al.

Summary: This study investigates the feasibility of using dielectric barrier discharge plasma actuation for pitch stability control on a NACA 0012 airfoil at low Reynolds number. The results show that the co-flow plasma actuator configuration is more effective in controlling pitch instability, reducing the energy extracted by the airfoil from the flow over one oscillation cycle by 726% relative to the baseline case. The plasma flow control is found to be effective in mitigating pitch instability across a wide range of Reynolds numbers.
