Special Issue Information

Dear Colleagues,

Dielectric barrier discharge (DBD) plasma actuators are innovative devices with proven effectiveness for various active flow control applications. In addition, their suitability has recently been demonstrated for heat transfer applications, such as film cooling enhancement, deicing or ice accumulation prevention. These devices have very interesting characteristics such as very low mass, low power consumption, low cost, fully electronic, fast response time and easy implementation, even in surfaces with complex shapes. In this context, it is very important to further investigate the implementation, optimization and physics of operation of surface DBD plasma actuators for thermo-fluid dynamics applications. In the current Special Issue therefore, we aim to collect innovative experimental, numerical or theoretical studies on dielectric barrier discharge plasma actuators, including the physics behind their operation, thermal and/or aerodynamic performance improvements, new configurations and/or operation modes and novel possible applications. Additionally, we also welcome discussions of simultaneous ice prevention and flow control, ice sensing, development of durable dielectric materials for DBD, new experimental techniques or numerical methods for DBD analysis, etc.

Plasma actuators have been proposed as a tool to produce hydrodynamical effects in the boundary layer of aerodynamical flows. We have analyzed some properties of these systems using suitable plasma diagnostics based on the emissivity characteristics of such plasmas. The direction and the velocity of propagation of the ionizing wave spreading on the dielectric surface were measured (in the 100–200 km/s range), and it was demonstrated that it behaves like a cathode-directed streamer. The averaged electron temperature (4–5 eV) and the reduced field strength (E/N ≈ 6 × 1019 V·m2) of the ionizing wave switching the discharges on were measured, too. Full article
