Introduction to DBD Plasma Flow Control
Dielectric Barrier Discharge (DBD) Plasma Flow Control represents a transformative leap in aerodynamic and fluid flow management technologies. Unlike conventional mechanical actuators, DBD plasma actuators use electrical energy to generate plasma—a partially ionized gas—near solid surfaces, such as aircraft wings, turbine blades, or vehicle bodies. This plasma creates localized body forces that actively influence the boundary layer behavior and overall flow field, enabling precise control over airflow characteristics without any moving parts.
