In recent years, the application of innovative technologies in the field of aerospace, such as laminar flow control, composite materials, and all-electric drives, seems to be a great challenge to traditional anti-icing systems. A new concept of anti-icing based on Alternative-Current-driven Surface-Dielectric Barrier Discharge (AC-SDBD) plasma actuation is developing by the applicant and his team. This method has no complicated mechanical structure and potential aerodynamic loss and can satisfy the new demand for anti-icing methods due to the development of innovative technologies. At present, the feasibility and effectiveness of anti-icing using AC-SDBD plasma actuation have been verified. However, due to the strong multi-physics coupling characteristics and multi-time-scale processes shown in the plasma anti-icing process, the mechanism of actuation is not yet clear. This project intends to study on exploring (1) plasma aerodynamic actuation and thermal actuation coupling mechanism; (2) plasma anti-icing mechanism based on multi-physics coupling effects. This project intends to study (1) the coupling mechanism of plasma aerodynamic and thermal effect; (2) the characteristics and mechanism of anti-icing for plasma multiphysics coupling effects; (3) the integrated design of plasma actuation anti-icing and flow control. This research includes many frontiers of fluid mechanics such as plasma physical characteristics, flow control mechanism, icing mechanism, anti-icing mechanism, etc. It has important research value and good application prospects in the field of aviation and aerospace.
