According to recent results in literature, the use of plasma actuator is a relevant technique to modify the aerodynamic characteristics of a vehicle and to decrease the energy consumed for a displacement. But this gain on fuel consumption must not increase pollution due to the electric discharge in air. So this study focuses on the ozone produced by the most commonly used plasma actuator (sinusoidal driven surface dielectric barrier discharge) for different configurations and operating parameters. Although ozone production is much weaker from a SDBD actuator compared to a DBD-based ozonizer, our results show that ozone production is not negligible and must be taken into account in plasma actuator developments for vehicle applications.
